Re: Calculate MACs in MATLAB

Agree the tic toc is useful but I am doing one method by hand and the
other practically on matlab so I can't use it.

Well, you can time your functions then use an approximation to calculate
the equivalent FLOP count. FFTW uses MFLOPS = 5*N*log2(N)/time (in us) for
complex data, divide by 2 for real data. You can force MATLAB to use FFTW,
though I do not know if there are any timing differences between FFTs
within MATLAB, or whether the command-line executable for FFTW is faster or
slower.
