I am trying to find the local minimum of a function using Minimize function in Mathcad 15. I would like to use the Levenberg-Marquardt algorithm. However, I am unable to select this option from the menu, see the image below.
Please let me know if it is poosible with Minimize function.
From Mathcad (11) Help. I suspect Mathcad 15 will be little different:
"Conjugate gradient method for solving
Means that the Conjugate gradient method can be used for Minimize.
Means that the LM method canNOT be used for Minimize.
The Mathcad 15 help is indeed different and if you read the section describing the various algorithms you may get the impression that LM is available with minimize, too. But then the help section for minimize and maximize clearly states:
