Extract data from fileDatastore and cell

read(fds)

ans =

struct with fields:

data: {178093×3 cell}

Cell data is somthing like that

{1×1×9 double} {10×20×3 single} {[0.4343]}

How can extract all rows and but 1 and 3 number columns such as only {1×1×9 double} {[0.4343]} using fds.data ?

To extract specific columns (in your case, columns 1 and 3) from a cell array and obtain all rows, you can use MATLAB's cell array indexing. Given that fds.data is a cell array with dimensions {178093×3}, you can extract the desired columns as follows:

% Extract all rows but only columns 1 and 3

extractedData = fds.data(:, [1, 3]);

% Display the size of the extracted data to confirm

disp(size(extractedData));

% Display the first few rows of the extracted data to verify

disp(extractedData(1:5, :));
