Class AdaptiveModel

java.lang.Object
  pacemaker.AdaptiveModel

public class AdaptiveModel
extends java.lang.Object

Useful static code related to Phase Response Curve (PRC) related to "ADAPTIVE" model (Ermentrout, 1991) .

The implementation for g⁺ and g^- functions (as definited in the paper) are provided. They are really easy max/min single line ops when it is recognized that they have a common core, this is implemented in fcore() core = 1/(2*pigreco) * sin(2*pigreco*phase)

Constructor Summary

public AdaptiveModel()

Method Detail

fcore

public static double fcore(double phase)

Evaluate the common core of g⁺ and g^- functions:

= 1/(2*pigreco) * sin(2*pigreco*phase)

Parameters:

phase - - the phase (x value) proportional to period. In range [0,1].

gplus

public static double gplus(double phase)

Evaluates the g⁺ function.

g+(x) = max(fcore(x), 0)

Parameters:

phase - - the phase (x value) proportional to period. In range [0,1].

gminus

public static double gminus(double phase)

Evaluates the g^- function.

g-(x) = max(fcore(x), 0)

Parameters:

phase - - the phase (x value) proportional to period. In range [0,1].

eval_PRC

public static double eval_PRC(double phase,
                              int period,
                              int max,
                              int min)

Evaluates the PRC for the given phase.

Parameters:

phase - - the phase (x value) proportional to period. In range [0,1].

Returns:

PRC evaluation (y value): in range [0,1].

main

public static void main(java.lang.String[] args)
