TimeInterpolate
2D/3D• TimeInterpolate[expr, {rules1, rules2, ... }] returns an InterpolatingFunction object representing expr as a function of time.
• Each of the rulesi must be a list of rules containing numerical replacements for all of the subexpressions in expr, as well as a rule for the value of time T. • TimeInterpolate accepts the InterpolationOrder option.
• If higher-order (velocity or acceleration) terms are included in the rulesi, TimeInterpolate automatically calculates the time derivatives of expr and uses the values of the higher-order terms supplied in rulesi to produce a higher-order InterpolatingFunction.
• The default option InterpolationOrder->Automatic is equivalent to three for zeroth- and first-order data and five for second-order data.
• See also: Interpolation, SolveMech. Further Examples Load the Modeler2D package and define a simple model. SolveMech is used to get a nested list of rules giving the value of time, and the value of all the variables in the model.
