I just want to measure flops in a programme, e.g.
flops(0)
W = zeros(k,n);
flops
But I get the error message "Unrecognized function or variable 'flops'." And I don't understand this. "flops" is a normal function defined by default in Matlab. I use Matlab R2021a.

flops() was removed from MATLAB 20 years ago.

The flops function was removed from MATLAB in version 6.0 in 2000. There are some user contributed replacements but they all have limitations.
