Data (.txt) into matrix

I have a set of data and I wanna convert it to a matrix in Matlab, so that i can see the model.

The data comes from a different program, and it is organized in a line, where the first number means the x variable, the second means the y variable, and the ";" separates the point.

How can I make a matrix out of it so that I can plot the model?

I've attached the first data.

Thank you very much.

I don't see any data attached.

Moved their attachment here, instead of as an "answer".

This works on the small file I attached here. If the format is not exactly what you have, maybe you can still figure out how to do it from this start.

fid = fopen('data.txt');
C = textscan(fid,'%f,%f;');
fclose(fid)

It seems to have worked on the file you uploaded as well. (Note that I moved your file to a comment on the question, instead of being an "answer".)
