MATLAB: How to load variable listed in folder one at a time and run a script sequentially

load variable sequence multiple

Dear all,

I have different .mat expressions (values) of the same variable VAR in a list of numerical arrays named differently stored in a folder: 'path to folder'\'array name'.VAR I want to import each VAR expression ('array name'.VAR) one at a time, run a script on the VAR value, name the output based on the 'array name' (such as 'array name'.OUTVAR), clear workspace except OUTVAR, then import the next VAR value on the list, run the same script, and iterate down the list. Please advise, I mention that 'array name' is not, say, 'file1', 'file2', but 'mark', 'john'

Many thanks,

Octavian

I suggest that instead of trying to create individual variables in the workspace for each array, that instead you use fields of a structure. For example,

ArrayName = 'mark';
results.(ArrayName) = ....

MATLAB: Batch import .mat and save every file into .csv

Instead of

    load ('fullFileName')
    csvwrite('fullFileName.csv', input1_t_)

try

    s = load ('fullFileName')
    data = s.input1_t_; % Or whatever it's called.
    % The output file name is the same except the .mat extension is replaced by .csv.
    fullOutputFileName = strrep(lower(fullFileName), '.mat', '.csv');
    csvwrite(fullOutputFileName, data)

MATLAB: Read images from folder

See the code snippet in the FAQ:

https://matlab.fandom.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

Which you'd adjust like this:

% Specify the folder where the files live.
myFolder = fullfile(pwd, '..\TRAINING SET');
% Check to make sure that folder actually exists.  Warn user if it doesn't.
if ~isfolder(myFolder)
    errorMessage = sprintf('Error: The following folder does not exist:\n%s\nPlease specify a new folder.', myFolder);
    uiwait(warndlg(errorMessage));
    myFolder = uigetdir(); % Ask for a new one.
    if myFolder == 0
         % User clicked Cancel
         return;
    end
end
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '*.BMP'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
for k = 1 : length(theFiles)
    baseFileName = theFiles(k).name;
    fullFileName = fullfile(theFiles(k).folder, baseFileName);
    fprintf(1, 'Now reading %s\n', fullFileName);
    % Now do whatever you want with this file name,
    % such as reading it in as an image array with imread()
    imageArray = imread(fullFileName);
    imshow(imageArray);  % Display image.
    drawnow; % Force display to update immediately.
end
