Fourier coefficients : fourier_an and fourier_bn or fourier_cn
Let f be a T-periodic continuous functions on
except maybe at a finite number of points.
One can prove that if f is continuous at x, then;
f (x) |
= |
+ ancos( ) + bnsin( ) |
|
|
= |
cne 2i nxT |
|
where the coefficients an, bn, n
N, (or cn, n
Z) are the
Fourier coefficients of f.
The commandsfourier_an and fourier_bn or fourier_cn
compute these coefficients.
