Consider the outer product X :$=$ xx$,$ x in Rn$,$ where Rn denotes the set of all n $\backslash$times $1$ vectors with real entries. Without using any loops $($such as for, while, if else$),$ we want to write a MATLAB function named SumOuterProduct.m that takes an arbitrary vector x in Rn as input and outputs the scalar s$,$ equal to the sum of all entries on or above the main diagonal of the matrix X$.$
