no_gradcheck
The no_gradcheck command is very similar to the newopt command
in its usage and arguments. It serves to check the analytic gradient
by a finite-differencing of the function-values for a
given function.
The arguments to the no_gradcheck function are given in the table
below:
Argument |
Argument type |
Mandatory |
Default |
To specify |
function= |
name of the function |
yes |
- |
type of problem for which
the gradient is checked |
del= |
real |
no |
0.001 |
displacement used in finite-differencing
of the function |
The function argument must be specified; the default value of
the del argument is 0.001.
