I have a .txt file i want to read. Each line has a character and then integers delimited by commas. I want to read the file so that i have an array which is number of fields by the number of lines in the file. Firstly i tried using load() but this doesn't deal with the characters. I have also tried textscan, specifying the format but that created a cell array which was 1 by number of fields. The file will look like this.

A,1,2

B,2,3

So in the example above i would like the file it to be stored in a 2x3 array for me to use the values.

With textscan use the 'collectoutput',true option to put the numeric values into one cell then convert to an array w/ cell2mat or just the {} nomenclature.
