FunctionVector

public FunctionVector()

FunctionVector

public FunctionVector(int size,
                      IgniteFunction<Integer,Double> getFunc,
                      IntDoubleToVoidFunction setFunc)

Creates read-write or read-only function vector.

Parameters:

size - Vector size.

getFunc - Function that returns value corresponding to given element index.

setFunc - Set function. If null - this will be a read-only vector.

Parameters:

size - Vector size.

getFunc - Function that returns value corresponding to given element index.

FunctionVector

public FunctionVector(Map<String,Object> args)

Parameters:

args - Arguments for vector constructor.

Method Detail

cols - Number of columns.

Returns:

New matrix.

times

public Vector times(double x)

Gets a new vector that contains product of each element and the argument.

Specified by:

times in interface Vector

Overrides:

times in class AbstractVector

Parameters:

x - Multiply argument.
