• Wikipedia: Determinant
• Youtube - The determinant | Essence of linear algebra, chapter 6
• Youtube - Cramer’s rule, explained geometrically | Essence of linear algebra, chapter 12

Examples

>> Det({{1, 1, 0}, {1, 0, 1}, {0, 1, 1}})
-2

Symbolic determinant:

>> Det({{a, b, c}, {d, e, f}, {g, h, i}})
-c*e*g+b*f*g+c*d*h-a*f*h-b*d*i+a*e*i
