How to process multiple sub - folders in main folder

Hi,

I'm currently in the process of processing data from 5 files within a folder. I have 1 main folder containing 8 subfolders, each containing 5 files. Right now im already able process the files within 1 single sub-folder to how i want. However I want to be able to process the each individual subfolder(Data type analysised is same for all subfolders). Sub folders are called (70ml, 80ml....).

Code: (For 1 sub-folder)

cd 'C:\Hello\A.......\70ml'; (Main Folder called 'C:\Hello\A' containing 'C:\Hello\A.......\70ml', 'C:\Hello\A.......\80ml' etc)

files = dir('*r.png');

compiledArr = zeros(8,5)

for i = 1:size(files)

filename = string(files(i).name);

imread(filename);

SummaryPage = imread(filename);

J = imresize(SummaryPage, 4);

roi = [1589 528 1376 1368];

ocrResults = ocr(J, roi);

for LC = 1:8

wordCells = ocrResults.Words;

tempStr = wordCells(LC);

tempStr = strrep(tempStr,",","");

tempNum = str2double(tempStr)

valArr(LC, 1) = tempNum

end

switch i

case 1

compiledArr(:, i) = valArr

case 2

compiledArr(:, i) = valArr

case 3

compiledArr(:, i) = valArr

case 4

compiledArr(:, i) = valArr

case 5

compiledArr(:, i) = valArr

end

end

Do you have any suggestions on how this could be done? Thank you!

Hi, i tried the code and repace with my own directories and such but i now have an error called

Index exceeds the number of array elements (1).

at this line tempStr = wordCells(LC);

Could it be because of i hardcoded at the switch part? any suggestion on improvement i can do
