P4 version 8.0.1-beta, July 2018 Pre-release

Pre-release

Changelog:

New features

P4 and P5 (https://www.uhasselt.be/UH/dysy/Software/P5.html) are finally merged into a single program. Now P4 can define and work with piecewise systems of planar differential equations, but also can compute per-vector field isoclines, and plot arbitrary curves on top of the study.
The complete list of changes is too big to be included here, since this release is almost written from scrap (but if interested you can see the commits section in the repository for a "list" of changes). Most changes are under-the-hood memory-management and code modernization to adapt P4 to the newest C++ and Qt standards.

Bug fixes

Fixed a bug from v8.0.0-beta that prevented users from computing arbitrary curves.

Dependencies changed

Boost library is no longer needed by P4.
Minimum Qt version required: Qt 5.5.0

Planned future features

Sadly, this is the last planned version of P4 since the maintainer will not be able to work on it anymore.

Linux

Installation instructions

Compile and install (recommended):

Check dependencies for Linux systems,
git clone https://github.com/oscarsaleta/P4.git && cd P4, or just cd into the P4 source directory if you already cloned this repository previously.
Optional: if you want exactly this version of P4 (v8.0.1-beta) and don't want to risk the possibility of installing a higher version of the software, do one of the following options
3.1 Using git: git fetch --all --tags --prune && git checkout tags/v8.0.1-beta -b local_v8.0.1-beta
3.2 Downloading source: download the compressed source code from the bottom of this page (zip or tar.gz format) and extract it,
Run ./compile_install_p4 and follow the instructions,
Done!

Binary install (needs at least Qt 5.9.5, see #Compilers used section):

Download P4_linux_v8.0.1-beta.tar.gz,
Extract the file (from command line: tar -xvzf P4_linux_v8.0.0-beta.tar.gz),
Copy the extracted folder to a place of your choice (we will call it /path/to/p4),
Create symlink for sumtables directory: ln -s /path/to/p4/sumtables /path/to/p4/sum_tables,
Add export P4_DIR=/path/to/p4 to your .bashrc (or to the configuration file for your specific shell)
Done!

Notice:

the compile and install method will install the latest version of P4 if done through git (skipping step 3), but if you use the git tag, .tar.gz or the binary methods, only this current version will be installed
the binary installation will not check for any dependencies and the program might not work for your system.
check out the FAQ if you have problems, or create an issue if your problem isn't answered there.

P4 version 7.0.1, November 2017 Latest

Latest

Changelog:

New features

The Save button now saves more! The parameters were already stored, but now also the current state and geometry of the main and plot windows are saved, and also all the zoom windows, output window (the output is stored and there is no need of re-evaluating), and view finite and infinite results panels. All is stored in a "name.conf" file besides the other files generated by P4, and loaded back when the Load button is pressed.
Now you can select the colour of the plots background between black (default) and white (which looks like the printed images). This setting is located in About P4... > Main settings.
Now you can also select the colour scheme of the printed images (black or white, same as with the plot window). This setting is located in the Print window that is open from the plot panel.

Removed features

Parameters and Vector field buttons, that were used to hide parts of the UI and were not really necessary.
The "small arrow button" that was used to hide all the UI except the top buttons and name field was also removed.

Improvements

The plot window now adapts to the size of the toolbars, so no buttons are hidden depending on the theme of the operative system.

Bug fixes

Due to an API change of Qt for versions > 5.5, there was an error in P4 v7.0.0-beta that prevented compilation in systems with older Qt versions. This has now been addressed.

New dependencies

Boost library is now needed by P4, because the implementation of the linked list of zoom windows (so we can keep track of the currently open zoom windows) was changed to a more robust one (and one that allowed saving and restoring the information from a file). The Unix compile-install script now checks for this dependency and suggest installation instructions if it is not found. Windows users won't need to worry about this dependency unless they want to compile P4 themselves.

Planned future features

Next major release (v8.x.x): we will integrate the P5 features (Piecewise P4) into this version of P4.

Known issues

Linux:
- There is a known issue that affects some Linux distributions and prevents the user from typing special characters such as ^ in the vector field input areas.
  - Workaround 1: type the vector field in another text editor and then copy-paste it to the P4 application.
  - Workaround 2: use ** instead of ^ for powers
Windows:
- The program can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer error when executing P4. The problem is that the Universal CRT (C Runtime) KB2999226, which is part of the Visual C++ Redistributable for Visual Studio 2015, failed to install.
  - Solution:
    1. Install Windows Updates (Start - Control Panel - Windows Update, check for updates, install all available updates, restart your computer, and after the restart repeat these steps until no further updates are available),
    2. Download the Visual C++ Redistributable (64-bit)
      1. Execute vc_redist.x64.exe and select uninstall.
      2. Execute vc_redist.x64.exe again and select install.

v5.0.0

db7d6b6

P4 Version 5.0.0, May 2017

Changelog

New feature: plot isoclines from the Plot window, selecting the Isoclines button and introducing a value for the slope. The range of values can be any double precision value, and the keyword inf, which plots the infinity-slope isocline. Isoclines work similarly to orbits, you can plot several of them and delete them one by one or all at once.
New feature: plot arbitrary curves from the Plot window, selecting the Curves button. Unlike with version 4.0.0, now arbitrary curves also follow a linked list structure, you can plot as many curves as you want and delete them using the buttons from the dialog.
Visual Update: the Output Window has the Terminate and Clear buttons on the bottom right side, and they do not cover the Maple output.
Visual Update: the Help files and images have been updated to be in line with the newer versions of P4. This also has made the program smaller overall, since new images are of lower file size (yet same quality).

To use this feature, go to Plot, click the Curve button, fill the forms, then click on Prepare in order to convert the curve equation to a C++ readable expression, and finally click on Plot to visualize it.
Several Reduce code functions have been removed from P4's executable (they are still commented in the code), so the binaries should be slightly smaller.

Known possible issues

Linux:
- There is a known issue that affects some Linux distributions and prevents the user from typing special characters such as ^ in the vector field input areas.
  - Workaround 1: type the vector field in another text editor and then copy-paste it to the P4 application.
  - Workaround 2: use ** instead of ^ for powers
Windows:
- The program can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer error when executing P4. The problem is that the Universal CRT (C Runtime) KB2999226, which is part of the Visual C++ Redistributable for Visual Studio 2015, failed to install.
  - Solution:
    1. Install Windows Updates (Start - Control Panel - Windows Update, check for updates, install all available updates, restart your computer, and after the restart repeat these steps until no further updates are available),
    2. Download the Visual C++ Redistributable (64-bit)
      1. Execute vc_redist.x64.exe and select uninstall.
      2. Execute vc_redist.x64.exe again and select install.
