Write a function diagDom
that determines if

is strictly row diagonally dominant by returning true or false.

Apply your function to the matrices

The MATLAB function call gallery(’neumann’,25) returns a sparse

matrix that results from discretizing a partial differential using a five-point finite difference operator on a regular mesh. Execute diagDom using the matrix
