#FAQ
How is matrix multiplication done? ▾
Each element in the result is the dot product of a row from the first matrix and a column from the second. For an m×n and n×p matrix, the result is m×p.
What is a matrix determinant? ▾
The determinant is a scalar value computed from a square matrix. For a 2x2 matrix [[a,b],[c,d]], it is ad−bc. A zero determinant means the matrix is singular (not invertible).
