WebThe laginterpdiff operator is used to evaluate spatial derivatives of the laginterp operator, which has been added in 5.6. Normally you would not use the laginterpdiff operator directly; rather, it will automatically be used to evaluate an expression that is a spatial derivative of a laginterp operator, such as ‘d(laginterp(order, expr), x)’.
