Description
The particular form of the search pattern is controlled by the
pattern_basis
specification. If pattern_basis
is coordinate
basis, then the pattern search uses a plus and minus offset in each
coordinate direction, for a total of 2n function evaluations in the
pattern. This case is depicted in Figure 5.3 for three coordinate
dimensions.
