Is textscan the correct command to use when importing data from text files into matlab. The command seems to work fine if I only have a vector in the text file, but if I have a matrix, matlab will change the structure of the data and store the matrix as a vector. Which command should I use if I'm importing data from text files within a loop where some of the text files include vectors and others include matrices?

You have to specify the right 'format', read example 8 to get an idea: http://www.mathworks.co.uk/help/techdoc/ref/textscan.html

So, if I have say 4 .txt files in a folder where 2 are column vectors and the other 2 are matrices I would have to use textscan twice in order to obtain all of the values. By using:
fid = fopen('...');
a = textscan(fid,'%f');
It returns the text files which should be matrices as one long vector.
I've decided to use dlmread seeing as the .txt files do not have any headings.
Headers do not matter, if you want 4 columns the right format is:
textscan(fid,'%f %f %f %f','Delimiter',''whateveryoulike')
or
textscan(fid,'%f',4,'Delimiter',''whateveryoulike')
