Description

derivate_funct_1dderivate_funct_1dderivate_funct_1dDerivateFunct1dDerivateFunct1d calculates the derivatives of the function FunctionFunctionFunctionFunctionfunction up to the second degree. It uses a finite difference approximation of order O(h^2). The derivative is also a function with the same sampling points as FunctionFunctionFunctionFunctionfunction. With the parameter ModeModeModeModemode, 'first'"first""first""first""first" and 'second'"second""second""second""second" derivatives can be selected.
