determinant of a matrix in matlab

To calculate the determinant of a matrix in MATLAB, you can use the det function. Here's the syntax:

main.m
A = [1 2 3; 4 5 6; 7 8 9]; % Example matrix
determinant = det(A); % Calculate determinant

In the above example, A is the matrix for which we want to calculate the determinant. The det function calculates the determinant of A, and the result is stored in the variable determinant. Change the matrix A to the desired matrix you want to calculate the determinant for.

Note that the det function works only for square matrices. If you try to calculate the determinant of a non-square matrix, MATLAB will throw an error.
