.SH "Detailed Description"
.PP 
The \fBPowellUpdate\fP class is used to specify a Powell hessian update\&. 

This hessian update method is the recommended method for use with transition state searches (the \fBEFCOpt\fP class can be used for transition state searches)\&.

.PP
Save the base classes (with save_data_state) and the members in the same order that the \fBStateIn\fP CTOR initializes them\&. This must be implemented by the derived class if the class has data\&. 
.PP
Reimplemented from \fBsc::HessianUpdate\fP\&.
