SciLab - A Small Sized Open-Source Alternative to MATLAB

Scilab is an open source, cross-platform numerical computational package and a high-level, numerically oriented programming language. It can be used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations, numerical optimization, and modeling and simulation of explicit and implicit dynamical systems. MATLAB code, which is similar in syntax, can be converted to Scilab. Scilab is one of several open source alternatives to MATLAB.

Scilab is a high-level, numerically oriented programming language. The language provides an interpreted programming environment, with matrices as the main data type. By utilizing matrix-based computation, dynamic typing, and automatic memory management, many numerical problems may be expressed in a reduced number of code lines, as compared to similar solutions using traditional languages, such as Fortran, C, or C++. This allows users to rapidly construct models for a range of mathematical problems. While the language provides simple matrix operations such as multiplication, the Scilab package also provides a library of high-level operations such as correlation and complex multidimensional arithmetic. The software can be used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations, and numerical optimization.

Scilab also includes a free package called Xcos (based on Scicos) for modeling and simulation of explicit and implicit dynamical systems, including both continuous and discrete sub-systems. Xcos can be compared to Simulink from the MathWorks.

As the syntax of Scilab is similar to MATLAB, Scilab includes a source code translator for assisting the conversion of code from MATLAB to Scilab. Scilab is available free of cost under an open source license. Due to the open source nature of the software, some user contributions have been integrated into the main program.

Graph Software: DPlot 2.2.7.6 (Portable)

DPlot is a general purpose plotting program designed for scientists, engineers, and students.

DPlot features multiple scaling types, including linear, logarithmic, and probability scales, as well as several special purpose plots: tripartite grids (shock spectra), grain size distribution plots, polar plots, contour plots of 3D data, and box-and-whisker plots and dot graphs of one or more 1D samples.

Manipulation functions include FFT, filtering, and smoothing.

Data can be input via a variety of file formats, copied from the clipboard, sent to DPlot from another program via dynamic data exchange, or generated by formula. Example Visual Basic and C demo driver programs (source and compiled executable) are included.

Features:

• Multiple Scaling Types
• Bar Charts
• Box-and-Whisker Plots
• Multiple Independent or Dependent Scales
• Contour Plots of 3D Data
• Number of Formats
• Generate Curves from Formulas
• Interpolate between Points

NOTE: This is a portable version, means just extract and use.
