% Import the file

rawData1 = importdata(fileToRead1);

% For some simple files (such as a CSV or JPEG files), IMPORTDATA might

newData1.(genvarname(name)) = rawData1;

% Create new variables in the base workspace from those fields.

vars = fieldnames(newData1);

for i = 1:length(vars)

    assignin('base', vars{i}, newData1.(vars{i}));
