2.3 DUIM-Geometry Module
invert-transform
Generic function
Summary
Returns a transform that is the inverse of the given transform.
Signature
invert-transformtransform => transform
Arguments
- transform
- An instance of type
<transform>.
Values
- transform
- An instance of type
<transform>.
Exceptions
If transform is singular, invert-transform signals the <singular-transform> error.
Note: With finite-precision arithmetic there are several low-level conditions that might occur during the attempt to invert a singular or almost singular transform. (These include computation of a zero determinant, floating-point underflow during computation of the determinant, or floating-point overflow during subsequent multiplication.) invert-transform signals the <singular-transform> error for all of these cases.

Description
Returns a transform that is the inverse of the transform transform. The result of composing a transform with its inverse is equal to the identity transform.
