MATLAB: How to copy a file from one folder to several folders with some change within the text

copyfilefolderMATLABmultiple

Suppose I have this situation,

Master folder > Folder1, Folder2, Folder3…..

Now in Folder1 I have one matlab script named m1.m

I want to copy this m1.m into all other folders with name as m2.m, m3.m….so on and also I want to change some text within the script when it copied into other folder.

How can I do this automatically with some script?

Thanks

This works. Adapt as needed:

% Create vector of folder numbers.
folderNumbers = 1 : 3	% However many you want.
% Specify input folder
inputFolder = pwd; % Or 'folder1', etc.
% Specify what file to copy.
fileNameToCopy = fullfile(inputFolder, 'test.m');
if ~isfile(fileNameToCopy)
	errorMessage = sprintf('File does not exist:\n%s', fileNameToCopy);
	uiwait(errordlg(errorMessage));
	return;
end
% Get the base file name
[f, baseInputFileName, ext] = fileparts(fileNameToCopy)
% File exists, so copy it to folders "Folder 1", "Folder 2", etc.
for k = 1 : length(folderNumbers)
	% Create the output folder name.
	thisFolder = sprintf('Folder %d', folderNumbers(k));
	if ~isfolder(thisFolder)
		mkdir(thisFolder);
		fprintf('Creating folder %s\n', thisFolder);
	end
	% Create the output file name.
	baseFileName = sprintf('%s %d%s', baseInputFileName, k, ext);
	thisOutputFileName = fullfile(thisFolder, baseFileName);
	% Now do the copy
	copyfile(fileNameToCopy, thisOutputFileName);
	fprintf('    Copied file "%s" to folder "%s" as "%s"\n', ...
		[baseInputFileName, ext], thisFolder, baseFileName);
end

MATLAB: Does image reading is wrong?fullFilename contains the path of the image along with image extension

Well what would you want it to contain? It sounds right to me. However this is wrong:

img=imread('fullFileName');

It should be without quotes. When you added single quotes around it, that make a literal string - the string was 'fullFileName' instead of 'F:\My Images\foobar.png' or whatever. Here is the fix:

img=imread(fullFileName);

MATLAB: Open a series of images and save them in another folder

See http://www.mathworks.com/matlabcentral/answers/13205#answer_18099 to format your code.

See the FAQ to process a sequence of images: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

You need to have two folder variables, one for input, and one for output. And you need two base file names, one for input and one for output. Then use full file to create two filenames:

fullInputFileName = fullfile(inputFolder, baseInputFileName);
fullOutputFileName = fullfile(outputFolder, baseOutputFileName);

baseInputFileName would be files(k).name.

See full demo below:

% Copies all the files from one folder to another folder.
clc;    % Clear the command window.
workspace;  % Make sure the workspace panel is showing.
format compact;
% Define input and output folders.
% CHANGE THESE FOLDER NAMES!!!!!!
inputFolder = pwd;
outputFolder = uigetdir(pwd);
if strcmp(outputFolder, inputFolder)
  errorMessage = sprintf('Error: the output folder must be different than the input folder');
  uiwait(warndlg(errorMessage));
  return;
end
% Check to see that both folders exist.
if ~isdir(inputFolder)
  errorMessage = sprintf('Error: The following input folder does not exist:\n%s', inputFolder);
  uiwait(warndlg(errorMessage));
  return;
end
if ~isdir(outputFolder)
  errorMessage = sprintf('Error: The following output folder does not exist:\n%s', outputFolder);
  uiwait(warndlg(errorMessage));
  return;
end
% Get a list of files to copy.
filePattern = fullfile(inputFolder, '*.*'); % All files.
% filePattern = fullfile(inputFolder, '*.m'); % m-files.
fileNamesToTransfer = dir(filePattern);
numFiles = length(fileNamesToTransfer);
% Do the copying.
for k = 1 : numFiles
  % Get the base file name.
  baseFileName = fileNamesToTransfer(k).name;
  % Create the full input and output filenames.
  fullInputFileName = fullfile(inputFolder, baseFileName);
  fullOutputFileName = fullfile(outputFolder, baseFileName);
  fprintf(1, 'Now copying file #%d of %d: %s to %s\n', ...
    k, numFiles, fullInputFileName, fullOutputFileName);
  copyfile(fullInputFileName, fullOutputFileName);
end
msgbox('Done copy files!', 'modal');
