Hellow everyone!

I am running a code to detect the fractures from image, in the mide of code, it asks me to load the mat file generated by this function, the mat file is present in the folder but still giving me an error that no file exisit.

Any suggestion?

If you drag the file into the command window, does it provide the same file path when it loads?

No, it does not give the complete path ( Please snapshot) , i have also tried to change the path as well.

Run this code.

topLevelFolder = 'C:\Users\Omer\Documents\MATLAB';
filePattern = fullfile(topLevelFolder, '**\*.mat')
fileList = dir(filePattern)
% Loop over them.
numFiles = length(fileList);
for k = 1 : numFiles
    thisFileName = fullfile(fileList(k).folder, fileList(k).name);
    fprintf('File #%d of %d :\n    "%s"\n', k, numFiles, thisFileName);
    % Get size info if desired
    d = dir(thisFileName);
    fprintf('    It is %d bytes.\n', d.bytes);
    s = load(thisFileName)
end

What do you see in the command window?

Should I use your code instaead of fileName = fullfile(outfolder, "shearletSystem" + i + ".mat")

load(fileName). Well, I used your code in command window and have got the following information;

K>> topLevelFolder = 'C:\Users\Omer\Documents\MATLAB';

filePattern = fullfile(topLevelFolder, '**\*.mat')

fileList = dir(filePattern)

% Loop over them.

numFiles = length(fileList);

for k = 1 : numFiles

thisFileName = fullfile(fileList(k).folder, fileList(k).name);

fprintf('File #%d of %d :\n "%s"\n', k, numFiles, thisFileName);

% Get size info if desired

d = dir(thisFileName);

fprintf(' It is %d bytes.\n', d.bytes);

s = load(thisFileName)

end

filePattern =

'C:\Users\Omer\Documents\MATLAB\**\*.mat'

fileList =

When you do

X = fftshift(fft2(ifftshift(X)));

it takes X and does operations on it and puts it back into X. So X must exist already. You must define it before you call that line.

Walter Roberson 2021-10-4

The error messages show that CSHRMsheardec needs to be called with at least one parameter, that it refers to as X, but that you ran the function with no parameters -- for example you might have pressed the green Run button instead of going down to the command line and invoking the function passing in values.

Do not use strcat() to create the path like that: you are missing a directory separator. Use

load( fullfile(outfolder, sheerletSystem, i + ".mat") )

I do not seem to find a complete posting of your code, for us to see where you define outfolder . In the previous comments, you never posted that part so we just had to assume that you had already defined it.
