ft_find_text_in_active_block.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 [line_numbers] = FT_find_text_in_active_block(block,searchtext)
% 
% Finds a search string in a block and returns the line numbers
% where it was found. This function differs from FT_find_text_in_block
% in that it excludes all comment lines in the search
%
% block: block structure
% searchtext: string, text to search for
% line_numbers, vector of integers, giving the lines in which 
%               searchtext was found
%
% Part of the SimTools package
