.SH DESCRIPTION
.IX Header "DESCRIPTION"
Here is a list of all the functions in this module :
.IP \(bu 4
\&\f(CWgsl_min_fminimizer_alloc($type)\fR
.IP \(bu 4
\&\f(CW\*(C`gsl_min_fminimizer_free\*(C'\fR
.Sp
Don't call this function explicitly. It will be called automatically in DESTROY for fminimizer.
.IP \(bu 4
\&\f(CW\*(C`gsl_min_fminimizer_set \*(C'\fR
.Sp
Don't apply this function twice to the same fminimizer. It will cause a memory leak. Instead of this you should create new fminimizer.
.IP \(bu 4
\&\f(CW\*(C`gsl_min_fminimizer_set_with_values\*(C'\fR
.Sp
Don't apply this function twice to the same fminimizer. It will cause a memory leak. Instead of this you should create new fminimizer.
