HAVSIN

 

The HAVSIN function interpolates between two markers using a trigonometric function. Generally, this function is used to link two markers in a gradual curve, similar to the Step and Step 5 functions.

Arguments definition

The input variable for the defined HAVSIN

•    Generally, this variable is time or a function that returns a real number.

The starting point for the HAVSIN function

The initial value for the input variable (within the range of x≤x0)

The ending point for the HAVSIN function

The initial value for the input variable (within the range of x≥x1)

 

Formulation

 

Example

HAVSIN (time, 1.0, 0.0, 4.0, 1.0)

•     x = time: Independent variable

•     x0 = 1.0: The x-value at which the HAVSIN function begins

•     h0 = 0.0: Initial value of the HAVSIN function

•     x1 = 4.0: The x-value at which the HAVSIN function ends

•     h1 =1.0 : Final value of the HAVSIN function
