In most cases variables have well defined type at runtime. ![]() However, code like the snippet above is rare. ![]() However, such implementation results in code that is not much faster than interpreted code. One can imagine using an object to represent variables (the object would carry a type and pointer to memory where data is stored) and assignement operator which would assign both value and type. What's the type of a? Compiler has to know the variable size and type to emit correct code. The main reason is that the variable types are determined at runtime. This is very tricky for dynamic languages such as Matlab (also Python, Perl, etc. The goal for using JIT (just-in-time compilation) is to speed up interpreted code by compiling it in run time. However, this is 21st century and we have better ways. The old view - almost always using clever indexing one can avoid loops. Matrix or index operations on the other hand turn into internal function calls and are fast. ![]() The main reason is that I got conditioned (like the generations of matlab users) that loops are really slow because they have to be interpreted. To sum it up, FreeMat Portable comes with a comprehensive suite of features for helping you carry out operations in a matrix-oriented development environment, and is suitable especially for power users.I started using Matlab circa version 4 and I still cringe every time I have to write a loop in Matlab. A powerful and reliable rapid engineering and scientific progression tool The application offers support for N-dimension array manipulation, 8-,16- and 32-bit integer types (signed and unsigned), 32- and 64-bit floating point types, and 64- and 128-bit complex types, built-in arithmetic options for manipulation of all supported data types, linear system of equations via divide operators, 2D plotting and image display, 3D plotting and visualization via OpenGL. Plus, you may clear the history, work with a path tool and save the transcript. You can use the built-in editor in order to generate M or plain text files, work on different documents at the same time thanks to the multi-tabbed layout, perform basic editing tasks (cut, copy, paste, delete), undo or redo your actions, as well as alter the text in terms of font, highlighting and indentation options.įurthermore, you are allowed to undo or redo your actions, make use of keyboard shortcuts for faster operations, find and replace data, comment or uncomment a region, increase or decrease the indent, and carry out several debugging processes, such as execute current buffer or selection, step over or into, set/clear debugging, and stop the debugging mode. The console where you are allowed to input information can be cleared with just one click, and you may adjust the font and size of the text, and scrollback size. You can show, hide or move the File Browser, History, Variable and Debug panels, as well as import data from M or plain text file format. This means that you are actually free to alter the layout according to your preferences. User-friendly layout and importing optionsįreeMat Portable delivers a clean GUI that is made up of several floating panels which can be moved to the desired position in the working environment. ![]() Copying it on a USB flash drive is also possible. It doesn’t store entries in your Windows registry and write configuration data in your computer, so you can run it without administrative privileges. Uninstalling the program can be done by deleting the files that you have grabbed from the Internet. You can run the utility on your system by simply opening the EXE file. The portable version of the programįreeMat Portable is designed as the portable counterpart of FreeMat. The tool comes with support for C, C++ and Fortran code, distributed algorithm, as well as plotting and visualization capabilities. FreeMat Portable is open-source numerical computing environment that bundles features similar to those found in MATLAB and GNU Octave.
