Synopsis

VALs = gf_global_function_get(global_function GF, 'val',mat PTs)
GRADs = gf_global_function_get(global_function GF, 'grad',mat PTs)
HESSs = gf_global_function_get(global_function GF, 'hess',mat PTs)

gf_global_function_get(global_function GF, 'display')

Description :

General function for querying information about global_function objects.

Command list :

VALs = gf_global_function_get(global_function GF, 'val',mat PTs)

Return val function evaluation in PTs (column points).

GRADs = gf_global_function_get(global_function GF, 'grad',mat PTs)

Return grad function evaluation in PTs (column points).

On return, each column of GRADs is of the form [Gx,Gy].

HESSs = gf_global_function_get(global_function GF, 'hess',mat PTs)

Return hess function evaluation in PTs (column points).

On return, each column of HESSs is of the form [Hxx,Hxy,Hyx,Hyy].

s = gf_global_function_get(global_function GF, 'char')

Output a (unique) string representation of the global_function.

This can be used to perform comparisons between two different global_function objects. This function is to be completed.

gf_global_function_get(global_function GF, 'display')

displays a short summary for a global_function object.
