polycoef (MathScript RT Module Function)
Owning Class: convert
Requires: Control Design and Simulation Module and MathScript RT Module
Syntax
polycoef
polycoef(direction)
Description
Specifies whether the polynomial function coefficients you enter are in descending or ascending direction. After you use this function to specify a direction, any transfer function models you create interpret the coefficients in the direction this function specifies. This function affects only the tf and sys_filter functions. You also can return the current direction by entering polycoef with no inputs.
