ListInterpolation

ListInterpolation[array]
constructs an InterpolatingFunction object which represents an approximate function that interpolates the array of values given.
ListInterpolation[array, {{xmin, xmax}, {ymin, ymax}, ...}]
specifies the domain of the grid from which the values in array are assumed to come.
  • You can replace {xmin, xmax} etc. by explicit lists of positions for grid lines. The grid lines are otherwise assumed to be equally spaced.
  • array can be an array in any number of dimensions, corresponding to a list with any number of levels of nesting.
