## Methods for Function solve

### Description

The `solve` methods for `pdMat` classes all use a single argument call. They return a matrix of the same class as `a`.

### Methods

a = pdBlocked, b = missing
  invert a `pdBlocked` object
a = pdDiag, b = missing
  invert a `pdDiag` object
a = pdIdent, b = missing
  invert a `pdIdent` object
a = pdLogChol, b = missing
  invert a `pdLogChol` object
a = pdMat, b = missing
  invert a `pdMat` object
a = pdNatural, b = missing
  invert a `pdNatural` object
