d = det(X) returns the determinant of the square matrix X. If X contains only integer entries, the result d is also an integer.

The determinant is computed from the triangular factors obtained by Gaussian elimination [L,U] = lu(A)

s = det(L) % This is always +1 or -1

det(A) = s*prod(diag(U))

The statement A = [1 2 3; 4 5 6; 7 8 9]

produces A =

1 2 3

4 5 6

7 8 9

This happens to be a singular matrix, so d = det(A) produces d = 0. Changing A(3,3) with A(3,3) = 0 turns A into a nonsingular matrix. Now d = det(A) produces d = 27.

How can I multiply functions in MATLAB?

To multiply functions in MATLAB, you can use the element-wise multiplication operator, which is represented by the symbol ".". This operator allows you to multiply corresponding elements of two arrays or matrices. Simply use the operator between the two functions you want to multiply, and MATLAB will perform the element-wise multiplication for you.
