How can break a 1D array to matrix?

I have a 1D array of length 153600 X 1. I want to break this array into 320 X 240 matrix how to do that . Value in the 1D array has been attached in a notepad.

Try this:

m = reshape(v, 320, []);

where v is your vector and m is your 2-D matrix.

m is becoming a size of 320 X 480

So do you want the left half of that

leftHalfImage = m(:, 1:240);

or the right half image

rightHalfImage = m(:, 241:end);
