Hello Everyone,
I read the discription of MATLAB built-in benchmark, which execute six tasks and evaluate the performance of PC.https://de.mathworks.com/help/matlab/ref/bench.html
One of these tasks is: FFT of long vectors and for this task perfomance factor is floating-point and irregular memory access. What is irregular memory access and why can FFT measure it?
Thanks!
