How to read a value at the end of char from a text file?

Hi; I have a text file that contains characters and values. I need some values at the end of the character. Example ;

 Number of windows=16 

I need to extract only the value '16' at the end of the "Number of windows="

You can find the file attached

Starting on row 10, your data is just numeric. Are you trying to read the data in the headerlines? Which ones are you wanting to read? All of them? Is the text always the same? Is the data you are wanting to capture always numeric?

Are the files "small" (< 1kB)? Then:

C     = strsplit(fileread(FileName), '\n');
Key   = 'Number of windows'
mKey  = strncmpi(C, ['# ', Key], length(Key) + 2);
Line  = C{m};
mEq   = strfind(Line, '=');
Value = sscanf(Line(mEq+1:end), '%g')

For larger files importing the complete file is a waste of time. Then:

Key = '# Number of windows'
fid = fopen(FileName, 'r');
if fid < 0
    error('File not found: %s', FileName);
end
ready = false;
while ~ready
    Line = fgetl(fid);
    if strncmpi(Line, Key, length(Key))
        mEq   = strfind(Line, '=');
        Value = sscanf(Line(mEq+1:end), '%g');
        ready = true;
    end
end
fclose(fid);
