The STEP function interpolates between two markers using a cubic polynomial. Generally, this function is used when linking two markers in a gradual curve.

Arguments definition
|
The variable for the defined STEP function • Generally, this variable is time or a function that returns a real number. |
|
The starting point of the STEP function. |
|
The initial value for the input variable (within the range of x≤x0) |
|
The ending point of the STEP function |
|
The initial value for the input variable (within the range of x≥x1) |
Formulation
Example
STEP(time, 1.0, 0.0, 4.0, 1.0)
• x = time: Independent variable
• x0 = 1.0: X-value at which the STEP function begins
• h0 = 0.0: Initial value of the STEP function
• x1 = 4.0: X-value at which the STEP functions ends
• h1 = 1.0: Final value of the STEP function
