G3 = gauss3D(sz_X, sz_Y, sz_Z, a, prec);returns a 3 dimensional matrix being a gaussian bell curve where the width in the (x/y/z)-dimension is proportional to 1/a(1), 1/a(2) and 1/a(3), respectively. "prec" is the data precision.Default is a=[2.5 2.5 2.5] and prec='double'Examples:Cubic-shaped... Platforms: Matlab

This function implements vectorized FFTs on a GPU. The answer is the same as the fft and ifft matlab functions.You need to install the GPUFFTW2.0 library of Naga K. Govindaraju http://gamma.cs.unc.edu/GPUFFTW/ . On Naga's wed site, you can see the system requirements. It works on linux and... Platforms: Matlab

An ADCARRAY object usually contains a memmapfile object, together with a scale and offset to convert the values stored on disc (and pointed to by the memmapfile object) to real world numbers which are returned as double precision. These can also be transformed by a function pointed to by a handle... Platforms: Matlab

The Linux Soft Real-Time Target is a target definition to Real-Time Workshop from Mathworks. The target uses the POSIX real-time clocks to generate periodic signals, to wake the model process at every time step. The process is changed to real-time highest priority defined by the scheduler, and... Platforms: Matlab

It is a hill climbing optimization algorithm for finding the minimum of a fitness function in the real space. The space should be constrained and defined properly. It attempts steps on every dimension and proceeds searching to the dimension and the direction that gives the lowest value of the... Platforms: Matlab

View factor is a MATLAB function that uses the CDIF (contour double integral formula) to calculates view factors between planar surfaces(polygons), no matter what are the shape and the orientation of the two figures.All you need to enter is the coordinates of the vertices that define the outlines...
