I'm having trouble importing an entire csv folder into matlab workspace. I created the file path for the numerous csv files but, do not know how to load them into the workspace next in order to filter and plot? Please advise.
myFolder = 'C:\Users\AbrahamCaceres\Documents\My Documents\Clean Data';
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();
if myFolder == 0
return;
end
end
filePattern = fullfile(myFolder, '**/*.csv');
theFiles = dir(filePattern);
for k = 1: length(theFiles)
baseFileName = theFiles(k).name;
fullFileName = fullfile('c:\','theFiles','matlab',baseFileName);
fprintf(1, 'Now reading %s\n', fullFileName);
% Move files into workspace? Then filter & plot data.
end

Use readtable, readmatrix, or readcell. My preference is readtable.

I used the code recommended. Making progress but all the files are combining together into one labeled data. My goal is to load the files seperately instead of as one. I have files labeled Refined1.csv and Raw1.csv and they are being combined together instead of seperate. What I tried below didn't make a difference as well.
fullFileName = fullfile(theFiles(k).folder,theFiles(k).name,filesep)

You need to implement some flow control based on the file name. See Ch 12 of MATLAB Onramp.
