This function checks that the point estimate is consistent with the bounds
and the non linear inequality constraints. It is usually called by
optimbase.checkx0 to check initial guesses.
Usage
optimbase.isfeasible(this = NULL, x = NULL)
Arguments
this
An optimization object.
x
The point estimate, i.e. a column vector of numerical values.
Value
Return a list with the following elements:
this
The optimization object.
isfeasible
The feasibility flag, either -1, 0 or 1.
Details
Returns 1 if the given point satisfies bounds constraints and inequality
constraints.
Returns 0 if the given point is not in the bounds.
Returns -1 if the given point does not satisfies inequality constraints.
