Calculate Inverse of a Positive-Definite Matrix
The positive-definite matrix represented by a is inverted and
assigned to a.
## S3 method for class 'pdMat' solve(a, b, ...)
a |
an object inheriting from class |
b |
this argument is only included for consistency with the generic function and is not used in this method function. |
... |
some methods for this generic require additional arguments. None are used in this method. |
a pdMat object similar to a, but with coefficients
corresponding to the inverse of the positive-definite matrix
represented by a.
