WebAdding all the elements of a matrix to itself would be the same as multiplying every cell in the matrix by 2, or multiplying the matrix itself by 2. You don't need to worry about the dimensions lining up because you are adding the same matrix to itself, and then you would simply multiply every cell in the matrix by 2.
