writing a function in matlab
显示 更早的评论
Hi!
I wrote this file to evalute some .TXT file.
I want to write it as a function. I dont know what to write as Input and Output
%
clear all
close all
clc
format long
for i=1:30
data=[];
fileID = fopen(['measurement_' num2str(i) '.txt']);
block = textscan(fileID, '%s','Delimiter','\n');
data=[data; block];
fclose(fileID);
compact_data=vertcat(data{:});
compact_data(1:29:end)=[];
compact_data(1:28:end)=[];
result_file=fopen(['result_probe_' num2str(i) '.txt'],'w');
fprintf(result_file,'%s\r\n',compact_data{1:1:end});
clear all
end
I wish you could help to transform this in a function whre i could give the input files ond get the result_probe files
Thank you

You can write your function like this:
function [out] = myfunction(filenums)
%
%
n = 0;
out = zeros(length(filenums),3);
for i=filenums
data=[];
fileID = fopen(['measurement_' num2str(i) '.txt']);
try
block = textscan(fileID, '%s','Delimiter','\n');
data=[data; block];
fclose(fileID);
compact_data=vertcat(data{:});
compact_data(1:29:end)=[];
compact_data(1:28:end)=[];
catch
end
try
result_file=fopen(['result_probe_' num2str(i) '.txt'],'w');
fprintf(result_file,'%s\r\n',compact_data{1:1:end});
fclose(result_file);
catch
n = n +1;
out(n,:) = [i, fileID, result_file];
end
end
end
Usage would be:
out = myfunction(1:30);
The inputs give you the option to select specific files, the output gives you an array that tells you which files were successfully opened. Any -1 in a column signifies that the corresponding file failed to open.
