x should be numerical vector or matrix.
- fft(x): fast Fourier transform of vector x. If x is
matrix or multidimensional matrix, return 2D or multidimensional transform.
- ifft(x): inverse fast Fourier transform of x.
- sum(x): sum of all elements of vector or matrix
- mean(x): mean of all elements of vector or matrix
- max(x): maximum of all elements of vector or matrix
- min(x): minimum of all elements of vector or matrix
- range(x): minumum and maximum of all elements of vector or matrix,
returned as a vector
- var(x): variance of all elements of vector or matrix
- stddev(x): variance of all elements of vector or matrix
- rowsum(x): sum of all elements in each row
- rowmean(x): mean of all elements in each row
- rowmax(x): maximum of all elements in each row
- rowmin(x): minimum of all elements in each row
- rowrange(x): minumum and maximum of all elements in each row
returned as a vector
- rowvar(x): variance of all elements in each row
- rowstddev(x): variance of all elements in each row
- columnsum(x): sum of all elements in each column
- columnmean(x): mean of all elements in each column
- columnmax(x): maximum of all elements in each column
- columnmin(x): minimum of all elements in each column
- columnrange(x): minumum and maximum of all elements in each column
returned as a vector
- columnvar(x): variance of all elements in each column
- columnstddev(x): variance of all elements in each column
