ComplexNDArrayUtil

public ComplexNDArrayUtil()

Method Detail

exp

public static IComplexNDArray exp(IComplexNDArray toExp)

expi

public static IComplexNDArray expi(IComplexNDArray toExp)

Returns the exponential of a complex ndarray

Parameters:

toExp - the ndarray to convert

Returns:

the exponential of the specified ndarray

center

public static IComplexNDArray center(IComplexNDArray arr,
                     int[] shape)

Center an array

Parameters:

arr - the arr to center

shape - the shape of the array

Returns:

the center portion of the array based on the specified shape

truncate

public static IComplexNDArray truncate(IComplexNDArray nd,
                       int n,
                       int dimension)

Truncates an ndarray to the specified shape. If the shape is the same or greater, it just returns the original array

Parameters:

nd - the ndarray to truncate

n - the number of elements to truncate to

Returns:

the truncated ndarray

padWithZeros

public static IComplexNDArray padWithZeros(IComplexNDArray nd,
                           int[] targetShape)

Pads an ndarray with zeros

Parameters:

nd - the ndarray to pad

targetShape - the the new shape

Returns:

the padded ndarray

doSliceWise

public static IComplexNDArray doSliceWise(ComplexNDArrayUtil.MatrixOp op,
                          IComplexNDArray arr)

Does slice wise ops on matrices and returns the aggregate results in one matrix

Parameters:

op - the operation to perform

arr - the array to do operations on

Returns:

the slice wise operations

doSliceWise

public static Object doSliceWise(ComplexNDArrayUtil.ScalarOp op,
                 IComplexNDArray arr)

Execute an element wise operation over the whole array

Parameters:

op - the operation to execute

arr - the array to perform operations on

Returns:

the result over the whole nd array
