Import Data Into Workspace Issue

Hello,

I need some help with the following situation:

1) I have a folder (bkg_folder) containing numerous .spe files.

2) I have a function (readSPE) which can read a .spe file and output a 3D matrix of values

3) I am trying to create a script which imports all the .spe files in bkg_folder into matlab and stores them as individual matrices. I'd like the names of these matrices to match the names of the corresponding files.

Here is what I have so far:

%Specify folder 
bkg_folder = 'C:\Users\Irwin\Desktop\Matlab\photon_count_project\Background';

%Ensure folder exists
  if ~isdir(bkg_folder)
    errorMessage = sprintf('Error: The following folder does not exist:\n%s', bkg_folder);
    uiwait(warndlg(errorMessage));
    return;
  end

%Generate List of All Files in Folder
  bkgPattern = fullfile(bkg_folder,'*.spe');
  bkg_files = dir(bkgPattern);

for i = 1:length(bkg_files)
    basebkgName = bkg_files(i).name;
    fullbkgName = fullfile(bkg_folder, basebkgName); 
    fprintf(1, 'Now reading %s\n', fullbkgName);
    image = readSPE(fullbkgName);
end

The issue I am encountering is having the readSPE function save each .spe file to a separate 3D matrix (which would be named the same as its corresponding file).

Please help, let me know if anymore information is necessary!

Thanks :)

You can use 'fileparts' command to get the name of the file:

[pathstr,name,ext] = fileparts(filename); % Read the file name

Process/read the data from the file

eval([matlab.lang.makeValidName(name) '=' data ';']); % Assign the value to a variable named 'filename'

See the following documentation link for more information:
