When using norm with matrices, is it the average?

No, it is not the average.
Assuming you intend the 2-norm, the norm of a matrix is the largest singular value.

In Laymen terms, norm is actually the absolute value of a vector or matrix. For example x1 = [2;1] norm (x1)= sqrt (2^2+1^2) = sqrt(4+1) = sqrt (5) = 2.2361

That is correct for the 2-norm of vectors, but not matrices.
