IshmaelLocator
Class IshLocHyperbProcess.TimeDiff_LM

java.lang.Object
  IshmaelLocator.LM
      IshmaelLocator.IshLocHyperbProcess.TimeDiff_LM

Enclosing class:

IshLocHyperbProcess

 class IshLocHyperbProcess.TimeDiff_LM
extends LM

Functions for running the LM algorithm.

fcn() calculates the difference between the time delay for point x and the time delay measured from the audio signal.

jacFcn is the Jacobian of fcn, i.e., the partial derivative of each time-difference function in each dimension.
