inverse_five_param_nonlinearity(y, params)

Five-parameter inverse non-linear function.

\[\left(\frac{y^{1/p_4} - p_0}{p_1 - p_2 y^{1/p_4}}\right)^{1/p_3}\]

Parameters:

• x – Input non-linear encoded value(s)

• params – Values of five parameters that define the function

Returns:

Output non-linear encoded value(s)
