Calculate FFT transform
util.FFT(mode = 1, tab1, tab2 = NA)
mode |
1 for Direct Transform and -1 for Inverse Transform |
tab1 |
Array containing the Real part of the complex array When both defined, arguments 'tab1' and 'tab2' should have the same dimension. |
tab2 |
Array containing the Imaginary part of the complex array. If not provided, the Imaginary part is considered as zero. When both defined, arguments 'tab1' and 'tab2' should have the same dimension. |
A list containing:
tab1 The Real part of the transformed complex values
tab1 The Imaginary part of the transformed complex values
