For starters apologies in advance if I'm in in the wrong NG.
Downloaded fftw and I'm trying to get an assessment on the output
surround the command 'bench -sib246'.
On my machine this outputs:
'lib' is not recognized as an internal or external command,
operable program or batch file.
option -s requires an argument
Problem: ib256, setup: 46.36 ms, time: 2.64 us, ``mflops'': 3881
a) I'm not following what the 46.36ms of 'setup' entails and the di
b) How is time measured here. Is this as simple as:
//start the clock
start = std::clock();
// stop the clock
elapsed = (diff_type)std::clock() - start;
elapsed /= CLOCKS_PER_SEC;
c) bench executed "in-place backward complex transform of size 256".
This in my view means an array length 256 of complex type. I suspect
the content is irrelevant? Just trying to get a feel for the 'what
the complex type entails'
