WebCalculate a determinant of the main (square) matrix. To find the 'i'th solution of the system of linear equations using Cramer's rule replace the 'i'th column of the main matrix by solution vector and calculate its determinant. Then divide this determinant by the main one - this is one part of the solution set, determined using Cramer's rule. WebThe null matrix can have an unequal number of rows and columns. The addition of a null matrix to any matrix does not change the matrix. The multiplication of a null matrix with any other matrix changes the matrix into a null matrix. The determinant of a null matrix is equal to zero. The null matrix is a singular matrix. Related Topics
