CURVE:CUBIC

Cubic curve with one independent variable. Input for a cubic curve consists of the curve name, the 4 coefficients, and the maximum and minimum valid independent variable values. Optional inputs for curve minimum and maximum may be used to limit the output of the performance curve. curve = C1 + C2*x + C3*x**2 + C4*x**3
