1. A matrix addition takes two input matrices A and B and produces one output matrix C. Each element of the output matrix C is the sum of the corresponding elements of the input matrices A and B, i.e., C[ill1 = A[i][j] +B[i][. For simplicity, we will only handle square matrices whose elements are single-precision floating-point numbers. Write a matrix addition kernel and the host stub function that can be called with four parameters: pointer- to-the-output matrix, pointer-to-the-first-input matrix, pointer-to-the-second- input matrix, and the number of elements in each dimension. Follow the instructions below: C. element. Fill in the execution configuration parameters for this design Write a kernel that has each thread to produce one output matrix row.
