In this exercise, the main code passes to the checkMatrix function a 2.dimensional array of integer numbers First, the CheckMatrix function checks if the array represents a square matrice number of rows equals number of columns) If the array is not square the furiction prints "NONE" and exits. Second, if the array is square, the function checks if it is diagonal or not. A suare matris diagonal when all elements other than the diagonal elements are zero. For example, the following matricina diagonal matric 300 020 S if the array is digortal the function prints 1 otherwise itprints Third, the function check the array o Astala matres a diagonal matrix with equivalent diagonal elements. For some the following mataascar matra 200
