problem.chgdeltatype

Purpose

Changes the type of the delta assigned to a nonlinear variable

Synopsis

problem.chgdeltatype (vars, deltatypes, values)

Arguments

Vars

Indices of the variables to change the deltas for.

DeltaTypes

Type if the delta variable:

0	Differentiable variable, default.
1	Variable defined over the grid size given in values.
2	Variable where a minimum perturbation size given in values may be required before a significant change in the problem is achieved.
3	Variable where a meaningful step size should automatically be detected, with an upper limit given in values.

Values

Grid or minimum step sizes for the variables.

Further information

Changing the delta type of a variables makes the variable nonlinear.
