Data Mining Algorithms In R/Packages/optimsimplex/Simplex gradient

Description
optimsimplex.gradientfv determines the simplex gradient of the function which is computed by the secondary functions optimsimplex.gradcenter and optimsimplex.gradforward.

Usage
optimsimplex.gradientfv(this = NULL, fun = NULL, method = "forward", data = NULL) optimsimplex.gradcenter(this = NULL, fun = NULL, data = NULL) optimsimplex.gradforward(this = NULL)

Value
optimsimplex.gradientfv returns a list with the following elements:
 * g A column vector of function gradient (with length this$n).
 * data The updated user-defined data.

optimsimplex.gradcenter returns a list with the following elements:
 * g A column vector of function gradient (with length this$n).
 * data The updated user-defined data.

optimsimplex.gradforward returns a column vector of function gradient (with length this$n).
