Fix for grid_split() for when the number of divisions is more than the total number of points.

The last divisions are discarded in this case.

Commit by bugman :: r67 /trunk/minfx/grid.py:

Added the function grid_point_array() for finding the minimum point in an array of grid points.

This allows for completely non-linear grid searches as each point is arbitrary.

Added support for constraints into grid_split(). Points which violate the...

Commit by bugman :: r66 /trunk/minfx/grid.py:

Added support for constraints into grid_split().

Points which violate the constraints are now eliminated prior to the grid subdivision.

Added the grid_split() generator function. This takes a linear gird, converts it...

Commit by bugman :: r65 /trunk/minfx/grid.py:

Added the grid_split() generator function.

This takes a linear gird, converts it to a linear array of points, and then splits these returning
each grid subdivision.

The optimisation output is more consistent. The numpy array has been even better...

Commit by bugman :: r57 /trunk/minfx/grid.py:

Redesigned the grid search function.

The grid_ops arg has been replaced by the more intuitive num_incs, lower and upper args fro the
number of increments, lower bound, and upper bound value lists respectively.

The new incs argument has been added to allow custom non-linear grid searches.

The new MinfxError system is now being used, and many arguments are being checked.

The docstring has been converted to epydoc format.

A MinfxError is now raised if the supplied minimisation algorithm cannot be...

Commit by bugman :: r56 /trunk/minfx/generic.py:

A MinfxError is now raised if the supplied minimisation algorithm cannot be identified.

Added a rudimentary error system.

Commit by bugman :: r54 /trunk/minfx/generic.py:

Removed the grid search option from the generic_minimise() function.

The minimisation options are too messy and inflexible. The grid search should be preformed by
direct calls to grid.grid().

Modified the grid search print out to indicated the number of grid points used.

Commit by bugman :: r53 /trunk/minfx/grid.py:
