I am using textscan to import a file. It has 40 columns, which means I use the following.
data = textscan(dataID, '%f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f');
However I'd like to shorten this up a bit, and go with this instead.
data = textscan(dataID, '%f', 40);
Unfortunately the two return different values and I can't for the life of me figure out why.

thisfmt = repmat('%f', 1, 40);
data = textscan(dataID, thisfmt);
When you use '%f', 40, then you instruct textscan to use "%f" 40 times total, which would just get you your first line.
