I have a 14x1 matrix, I don't know how to compute the squares of the residuals. thank you.

What do you mean by residual?

Do you mean you are fitting an equation? What MATLAB function(s) are you using to do that?

Is it a 7x1 or a 14x1 VECTOR anyway? We cannot read your mind.
To compute the sum of squares of residuals you...
1. Compute the residuals. Note that you cannot compute a residual without the existence of TWO sets of numbers, thus the actuals and the predicted.
2. Square them
3. Form the sum
In which step are you having problems?
