Constructor Detail

BinaryUfunc

public BinaryUfunc(jnumeric.BinaryFunction function)

Wraps a BinaryFunction into a universal function.

Parameters:

function - The function to wrap

Method Detail

__findattr_ex__

public PyObject __findattr_ex__(java.lang.String name)

Description copied from class: PyObject

Attribute lookup hook. If the attribute is not found, null may be returned or a Py.AttributeError can be thrown, whatever is more correct, efficient and/or convenient for the implementing class. Client code should use PyObject.__getattr__(String) or PyObject.__findattr__(String). Both methods have a clear policy for failed lookups.

Overrides:

__findattr_ex__ in class KeywordFunction

Returns:

The looked up value. May return null if the attribute is not found

outer

public PyObject outer(PyObject poa,
                      PyObject pob)

Takes the outer product of a and b. The new results shape will be the same as a.shape + b.shape (where plus means concatenate, not add!)

Parameters:

poa - PyMultiArray a

pob - PyMultiArray b

Returns:

Outer produce of poa and pob.

reduceat

public PyObject reduceat(PyObject po,
                         int[] indices,
                         int axis)

This is a weird function, and most people should just ignore it. It will reduce a to each of the given indices so that as new size along the given axis will be the same as the length of indices. If axis is not supplied it defaults to zero.

Parameters:

po - Input PyMultiArray

indices - The indices to reduce to

axis - Axis along which to reduce (default: 0)

Returns:

The reduced array, with size == indices.length

reduceat

public PyObject reduceat(PyObject po,
                         int[] indices)

Overloaded function for if no axis is passed. Defaults to 0.

Parameters:

po - Input PyMultiArray

indices - The indices to reduce to

Returns:

result of reduceat(po, indices, 0)

See Also:

reduceat(PyObject, int[], int)

reduce

public PyObject reduce(PyObject po,
                       int axis)

Works just like reduce(ufunc, a, [ufunc's identity element]) except you get to choose the axis to perform the reduction along. Note that if the length of a long axis is 0, then the appropriate identity element for the ufunc will be returned.

Parameters:

po - Input PyMultiArray

axis - Axis along which to reduce (default: 0)

Returns:

Result of reducing the ufunc

reduce

public PyObject reduce(PyObject po)

Overloaded reduce, defaults axis to 0.

Parameters:

po - Input PyMultiArray

Returns:

Result of calling reduce(po, 0)

See Also:

reduce(PyObject, int)

accumulate

public PyObject accumulate(PyObject po,
                           int axis)

This is the same as reduce, except that all the intermediate results are kept along the way.

Parameters:

po - Input PyMultiArray

axis - Axis over which to reduce (default: 0)

Returns:

The intermediate results of reducing po

accumulate

public PyObject accumulate(PyObject po)

Overloaded accumulate, defaults axis to 0.

Parameters:

po - Input PyMultiArray

Returns:

Result of calling accumulate(po, 0)

See Also:

accumulate(PyObject, int)

_call

public PyObject _call(PyObject[] args)
