Find a numerical approximation to the inverse Fourier sequence transform of a periodic function
ResourceFunction["NInverseFourierSequenceTransform"][expr,ω,n] gives a numerical approximation to the inverse Fourier sequence transform of expr, evaluated at the integer n. |
Numerical value for a sequence with a given Fourier sequence transform:
In[1]:= | ![]() |
Out[1]= | ![]() |
Compare with the answer from symbolic evaluation:
In[2]:= | ![]() |
Out[2]= | ![]() |
In[3]:= | ![]() |
Out[3]= | ![]() |
