interpolant.RdAn interpolant is a function returned by ipol which has prespecified values in some
points, and which fills in between with some reasonable values.
The argument of the function. A function of more then one variable takes a
vector. x can also be a matrix of column vectors.
The number of threads to use for evaluation. All interpolants created by
ipol are parallelized. If given a matrix argument x, the vectors can
be evaluated in parallel.
Other parameters. Currently used for simplex linear interpolants with the logical argument
The "multilinear" interpolant also has the argument blend=c("linear","cubic","sigmoid") where a
blending function can be chosen.
A numeric. If more than one point was evaluated, a vector.
