%
% Inputs:
% uniform_ps: a structure where each field has the same nrows-by-ncols matrix. This function does NOT work
% if each field has different data types.
% Outputs:
% uniform_cell: nfields cells where each cell has a nrows-by-ncols matrix.
% uniform_matrix3D: 3-D array: nrows-by-ncols-by-nfields
