I am doing a project in matlab to compare the computational complexities of two systems the problem I have is that I need to work out how many multiply and adds a 150 point ifft uses in matlab from what I can work out MATLAB uses the Prime Factor algorithm to do this but I am having trouble working out how many MACS are done. Does matlab have the ability to feed back this information? Thanks ...

Hello Everyone, I am new to the site so bare with me. I am working on a college project involving convolution operations on complex 2D data. The original code for this program was written in Matlab and the C/C++ code that I am developing has to match the Matlab Implementation. So far I have been able to replicate the same data in Matlab except for the output from the Matlab FFT. When I use the ...

Hello all, I have never used the MATLAB engine from C before. I have a very basic question: What exactly is the benefit of this? To provide some more detail, for example, if I were to perform a conjugate multiply of two very large arrays, MATLAB would typically barf because of "out of memory" issues. Would running MATLAB functions "behind the scenes" by invoking the engine help in this ...
