Don't use path for the name of your folder because path is a built-in variable name. Try this:
[baseFileName, folder] = uigetfile('*.csv');
if isequal(baseFileName, 0)
disp('User did not pick a file');
return;
end
fullFileName = fullfile(folder, baseFileName);
disp(['Selected WRxx ',fullFileName]);
WRxx_0_00A = readmatrix(fullFileName,'Range','A3:D16003'); % Load data into variable.
or better:
% Have user browse for a file, from a specified "starting folder."
% For convenience in browsing, set a starting folder from which to browse.
startingFolder = pwd; % or 'C:\wherever';
if ~isfolder(startingFolder)
% If that folder doesn't exist, just start in the current folder.
startingFolder = pwd;
end
% Get the name of the file that the user wants to use.
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uigetfile(defaultFileName, 'Select a file');
if baseFileName == 0
% User clicked the Cancel button.
return;
end
fullFileName = fullfile(folder, baseFileName)
fprintf('Reading in "%s".\n', fullFileName)
WRxx_0_00A = readmatrix(fullFileName,'Range','A3:D16003');
