ft_find_text_in_all_blocks.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 [block_index, line_start, line_stop, line_numbers] = FT_find_text_in_all_blocks(blocks,searchtext)
% 
% Finds a search string in a block and returns the line numbers
% where it was found.
%
% blocks: vector of block structure
% searchtext: string, text to search for
% block_index: vector of integers, givin the blocks in which the text 
%              was found
% line_stop, vector of integers pointing into line_numbers, see below
% line_start, vector of integers pointing into line_numbers, see below
% line_numbers, vector of integers, giving the lines in which 
%               searchtext was found
%
% So, if lines 2 and 5 of block 3 contained the text the solution will include
% block_index(i)=3
% line_numbers(line_start(i):line_stop(i))= [2 5]
