FreeMat Portable 2j451j

FreeMat is a free environment for rapid engineering and scientific prototyping and data processing. It is similar to commercial systems such as MATLAB from Mathworks, and IDL from Research Systems, but is Open Source.

• N-dimensional array manipulation (by default, N is limited to 6)
• for 8,16, 32, and 64 bit integer types (signed and unsigned), 32 and 64 bit floating point types, and 64 and 128 bit complex types.
• Built in arithmetic for manipulation of all ed data types.
• for solving linear systems of equations via the divide operators.
• Eigenvalue and singular value decompositions
• Full control structure (including, for, while, break, continue, etc.)
• 2D plotting and image display
• Heterogeneous array types (called “cell arrays” in MATLAB-speak) fully ed
• Full for dynamic structure arrays
• Split-radix based FFT
• -by-reference (an IDL feature)
• Keyword (an IDL feature)
• Codeless interface to external C/C++/FORTRAN code
• Native sparse matrix
• Function pointers (eval and feval are fully ed)
• Classes, operator overloading
• 3D Plotting and visualization via OpenGL
• Handle-based graphics
• 3D volume rendering capability (via VTK)
