- Invert[Matrix]
- Inverts the given matrix.
- Example:
Invert[{{1, 2}, {3, 4}}]gives you the inverse matrix\begin{pmatrix} -2 & 1\\ \frac{3}{2} & -\frac{1}{2} \end{pmatrix}
.CAS Syntax
- Invert[Matrix]
- Inverts the given matrix.
- Example:
Invert[{{a, b}, {c, d}}]gives you the inverse matrix\begin{pmatrix} \frac{d}{a* d- b* c} & \frac{-b}{a* d- b* c}\\ \frac{-c}{a* d- b* c}& \frac{a}{ a* d- b* c} \end{pmatrix}
