# ListInterpolation

ListInterpolation[array]
constructs an InterpolatingFunction object that 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.

## Details and OptionsDetails and Options

• You can replace etc. by explicit lists of positions for grid lines. The grid lines are otherwise assumed to be equally spaced.
• ListInterpolation[array] assumes grid lines at integer positions in each direction.
• array can be an array in any number of dimensions, corresponding to a list with any number of levels of nesting.
• ListInterpolation[array,domain] generates an InterpolatingFunction object that returns values with the same precision as those in .
• ListInterpolation supports a Method option. Possible settings include for spline interpolation and for Hermite interpolation.
