- Invert[Matrix]
- Inverts the given matrix.
- Example:
Invert[{{1, 2}, {3, 4}}]gives you the inverse matrix\begin{pmatrix} -2 & 1\\ 1.5 & -0.5 \end{pmatrix}
.CAS Syntax
- Invert[Matrix]
- Inverts the given matrix.
- Example:
Invert[{{a, b}, {c, d}}]gives you the inverse matrix\begin{pmatrix} d/( a* d- b* c & -b/( a* d- b* c)\\ -c/( a* d- b* c) & a/( a* d- b* c) \end{pmatrix}
.
