---|---|---|---|---|
Required (Choose One) | Pattern Basis Type (Group 1) | coordinate | Use coordinate directions as search pattern | |

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.
