Write a for loop that converts the Data (Data.data) in the text file into matrix of 13 by 31 or 31 by 13.

The data should be imported and converted into a matrix of 13 x 31.

This should be one way:

alltext = split(fileread('Textfile.txt'),newline);
allnums = regexp(alltext(1:end-1),'(?<=:\s*)[+-E\d]+','match');
allnums = cellfun(@str2double,allnums);
allnums = reshape(allnums,13,[])

[Tunde Adubi]

Yeah, but let it be done with a for loop.

for k = 1
    alltext = split(fileread('Textfile.txt'),newline);
    allnums = regexp(alltext(1:end-1),'(?<=:\s*)[+-E\d]+','match');
    allnums = cellfun(@str2double,allnums);
    allnums = reshape(allnums,13,[])
end
