Workspaces contain variables that you create within MATLAB or import from data files or other programs. Variables that you assign through the Command Window or create by using scripts belong to the base workspace. Variables that you create in a function belong to their own function workspace. You...
% Note: We don't have to use rowfun, we may create the file name inside the loop. T2 = rowfun(@(x) {fullfile('E:', [x, '.txt'])}, T, 'InputVariables', 'Code', 'OutputVariableName', 'filename', 'ExtractCellContents', true); ...
