Hello, I have a gui with a multiline edittext box and I want for example to write on three lines 9 numbers (3 numbers on each line) and to create a 3x3 matrix. How can I do that? I know that an edittext box get strings but how can my program count the written lines of my edittext, and then create a matrix with the transformed strings to numbers?

kind regards!

get(EditBoxHandle, 'String') is going to return a cell array of strings. length() of the cell array will tell you how many lines there are.

You will need to convert the strings to numbers. See sscanf()

Thank you for your answer, instead of sscanf() I used the str2num(). The results were a little bit better.
