I have a .m file which can read data in .3ddose file (this is output data file from some simulation) and displays in the "Command Window" page of Matlab. Is there any way to write this displayed data into other text file?

function m = ReadEppOutput(file) % open the file f = fopen(file, 'rb'); % read two integers which give the size of the image size = fread(f, 2, 'int'); % initialize the output matrix m = zeros(size(1), size(2)); % read the rows into the matrix for x = 1:size(1) m(x,:) = fread(f, size(2), 'single'); end

end

在 MATLAB Online 中打开

function m = ReadEppOutput(file) 
  f = fopen(file, 'rb'); 
  size = fread(f, 2, 'int');

Do NOT use size as a variable--that aliases the builtin Matlab function of the same name which is far too commonly used to get into such bad habits. Use something else for the variable here -- siz or sz or anything but size.

    m = zeros(size(1), size(2)); 
    % read the rows into the matrix 
    for x = 1:size(1)
      m(x,:) = fread(f, size(2), 'single'); 
    end

Why read the array row by row? Just read the array in one swell foop...

m=fread(f,[sz(2),inf],'single')';
f=fclose(f);                        % close the input file

To write it as a formatted file simply open a new file for writing and use fprintf() with appropriate formatting or one of the other higher-level i/o functions to write a csv file or however desired.

end

Hi, I think that at the first step you have to read the data to matlab variable first. I've write matlab code to read specific line of .3ddose data. You can read the tutorial here and download the code here .
