READ THE ERROR MESSAGE! God gave us error messages so that we could read them. Ok, Cleve did. Same thing wrt MATLAB.
Some lines in your file do not have the same number of elements, but you are trying to merge them all into one flat array. Arrays in MATLAB all must have the same number of elements in each row. They are rectangular. Your file is apparently not.
And learn to use proper formatting for your code when you paste it in. I had to do that myself just to read what you had done.
