Armadillo ifft dimension

犰狳ifft support "dim" as Octave/Matlab吗?

Armadillo 文档显示为 "If given a matrix, the transform is done on each column vector of the matrix"。所以,不,它不支持 dim,但您可以将 Armadillo 的 ifft() 方法视为 Octave/MATLAB 的 dim = 1(列)。

如果您想对行执行 ifft(),那么您只需转置输入矩阵...

mat X; // This is the matrix you want to call ifft() on.
// The second transpose is optional, but it will get the Y matrix to have 
// the same dimension as the X matrix.
mat Y = ifft(X.t()).t();
