Method Detail

diffract

public abstract void diffract(double[][] field)

Performs numerical diffraction of the complex data in field, leaving the result in field. The physical layout of the complex data must be the same as in JTransforms:

field[i][2 * j] = Re[i][j], field[i][2 * j + 1] = Im[i][j]; 0 <= i < M, 0 <= j < N

Parameters:

field - The complex field to diffract.
