Noting also that between the endpoints of the DFT periodic input, there is the
interval of one sample.

Samuel,
The idea and the implementation of the end-points interpolation is that this is
done on the input data (big slope), not on the FFT output. Maybe be it needs
some further work. Tbc.

Rafael,
To me, this attempt looks not legitimate.
Indeed, the true original signal HAS a steep jump across its edges.
So, the best algorithm should shift the signal and *keep this big slope**
**from one sample to the next*. The jump is /*at least*/ as steep as from
one sample to the next (and li
Hello Rafael,
I did not remember this symetrization trick that you use to restore
continuous boundaries and so avoid the noise-making jump.
It is very efficient. Great!
I don't see any reason that could make this trick failing with complex
numbers:
Making the signal even makes its spectrum ev

I could get a correct behaviour with your code. However, if you run

Never mind previous question, these files can be read very fast with the

Hello,
I wish to use orthogonal polynmials within Scilab. Axxording to

and I get the answer

Dear Scilab'ers,
Has anyone come across wrapped numeric input files, where the data spans over
thousands of lines?
It takes ages using loops to read data like in example below with 20 input
curves with index support from 1 to 4200 spreading over >20,000 lines:
