det - Compute the determinant of symbolic matrix
Syntax
r = det(A)
Description
r = det(A) computes the determinant of A,
where A is a symbolic or numeric matrix. det(A) returns
a symbolic expression for a symbolic A and a numeric
value for a numeric A.
Examples
Compute the determinant of the following symbolic matrix:
syms a b c d;
det([a, b; c, d])
The result is:
ans =
a*d - b*c
Compute the determinant of the following matrix containing the
symbolic numbers:
A = sym([2/3 1/3; 1 1])
r = det(A)
The result is:
A =
[ 2/3, 1/3]
[ 1, 1]
r =
1/3
