I have opened a file with a string consisting of three lines. I want to read these lines from the file and store them in my "template" variable as a three line string. All I can get is the last line of the string to be stored in "template"

    while feof(fid) == 0;
        line = fgets(fid);
        template = strvcat(line)
    end

Thanks for the help

在 MATLAB Online 中打开

template = {};
while feof(fid) == 0;
   template{end + 1} = fgets(fid);
end
templateChar = char(template);

More efficient:

C = textscan(fid, '%s', 'delimiter', '\n');
templateChar = char(C{1});

EDITED: textread -> textscan (Thanks, Jiro!)

@Jan, I think you meant to use "textscan", not "textread". "textread" requires the first input to be the actual file name, not the output of fopen. And "textscan" is preferred anyway.
