vlt.fit.naka_rushton_slope¶
vlt.fit.naka_rushton_slope - Evaluate slope of Naka Rushton function
R=vlt.fit.naka_rushton_slope (C, C50, N, S)
Returns the derivative of the Naka Rushton
function: d[C^N/(C^(N*S)+c50^(N*S))]/dc.
If S is not specified, S is assumed to be 1.
If C is negative, the result is negative.
