I tried using the sumsqr to sum squares of each element in a matrix I don't think I understand the syntax. I tried putting the matrix I into the command sumsqr(I), but I got the answer "1.3056e+010" and I don't know how to interpret this answer.

This is exponential format. You can print your variable in "normal" format with fprintf

1.3056e+010 is 1.3056 * 10^10

After modifying my code, I have a different answer. 7.4407e+006 Is this 7.4407*10^6 ?
