curve_4PL: 4PL model voltage curve

In csgillespie/voltagefit: Voltage Curve Fitting

Description

Model voltage curve based on the 4PL model. The first derivatives with respect to each parameter can also be calculated. NOTE: Here the data is shifted >> 0 in x, as the raw curve is not designed to handle x values of less than zero.

Usage

curve_4PL(x, param)

Arguments

x	a range of values for which the model curve is evaluated
param	list consisting of 4 parameters for the curve function: theta_1 Value of y at the curve minimum theta_2 Value of y at the curve maximum theta_3 Value of x (+100) at the point of inflection theta_4 A measure of the steepness of the curve

Value

A range of values, corresponding to the value of the 4PL curve for the given parameters, over the provided range of x values.
