DET | Determinant of a square matrix. |
| DET(matrix) |
DOT | Dot Product of two arrays, matrix1 matrix2. |
| DOT(matrix1, matrix2) |
EIGENVAL | Displays the eigenvalues in vector form for matrix. |
| EIGENVAL(matrix) |
EIGENVV | Eigenvectors and Eigenvalues for a square matrix. |
| Displays a list of two arrays. The first contains the |
| eigenvectors and the second contains the eigenvalues. |

INVERSE | Inverts a square matrix (real or complex). |
| INVERSE(matrix) |
LQ | LQ Factorization. Factors an m × n matrix into three |
| matrices: |
| {[[ m × n lowertrapezoidal]],[[ n × n orthogonal]], |
| [[ m × m permutation]]}. |
| LQ(matrix) |
LSQ | Least Squares. Displays the minimum norm least squares |
