ft_write_surface_map.m

用matlab做的Frequency domain INterferomEter Simulation SoftwarE,在国外网站下的,还在研究中,不会用,有会用的回复我

% function []=FT_write_surface_map(filename, map)
%
% Function for Matlab, writes array of real numbers to file.
% The array shoud represent either an amplitude or a phasemap of
% an optical surface.
% 
% filename: name of file to be written
% FT_map:   the surface map (variable must be a 'map' structure,
%           see FT_new_surface_map)
