# slpchgdeltatype

Purpose
Changes the type of the delta assigned to a nonlinear variable
Synopsis
`slpchgdeltatype(
prob,
varind,
deltatypes,
values,
nvars = x_max_vec_length(varind, deltatypes, values)
)`
Arguments

prob | The current SLP problem.
varind | Indices of the variables to change the deltas for.
deltatypes | Type of the delta variable: 0 (XSLP_DELTA_CONT) Differentiable variable, default. 1 (XSLP_DELTA_SEMICONT) Variable where a minimum perturbation size given in values may be required before a significant change in the problem is achieved. 2 (XSLP_DELTA_INTEGER) Variable defined over the grid size given in values. 3 (XSLP_DELTA_EXPLORE) 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.
nvars | The number of SLP variables to change the delta type for.

Return value
The input argument prob.
