public class Complex

Representation of a Complex number, i.e. a number which has both a real and imaginary part.

Based on The Apache Commons Mathematics Library http://commons.apache.org/math/

public static final Complex I

The square root of -1. A number representing “0.0 + 1.0i”

public static final Complex NaN

A complex number representing “NaN + NaNi”

public static final Complex INF

A complex number representing “+INF + INFi”

public static final Complex ONE

A complex number representing “1.0 + 0.0i”

public static final Complex ZERO

A complex number representing “0.0 + 0.0i”

public Complex(double real)

Create a complex number given only the real part.

Parameters:

  • real (double) – Real part.

public Complex(double real, double imaginary)

Create a complex number given the real and imaginary parts.

Parameters:

  • real (double) – Real part.

  • imaginary (double) – Imaginary part.

public Complex(String strVal)

Create a complex number from a String. Its syntax must be (without spaces):

  • <decimal number>+<decimal number>i

  • or (<decimal number>,<decimal number>i)

Parameters:

  • strVal (String) – string value.

public double getReal()

Access the real part.

public double getImaginary()

Access the imaginary part.

Vector types

All vector types provide the following methods:

Info

Not all array methods are documented.

public type getElementAt(int i, int j, int k, int h, int l, int m)

Get the value at the provided index.

Parameters:

  • i (int) – Index of first dimension.

  • j (int) – Index of second dimension (only for 2D+ vectors).

  • k (int) – Index of third dimension (only for 3D+ vectors).

  • h (int) – Index of fourth dimension (only for 4D+ vectors).

  • l (int) – Index of fifth dimension (only for 5D+ vectors).

  • m (int) – Index of sixth dimension (only for 6D vectors).

public void setElementAt(int i, int j, int k, int h, int l, int m, type element)

Set the value at the provided index.

Parameters:

  • i (int) – Index of first dimension.

  • j (int) – Index of second dimension (only for 2D+ vectors).

  • k (int) – Index of third dimension (only for 3D+ vectors).

  • h (int) – Index of fourth dimension (only for 4D+ vectors).

  • l (int) – Index of fifth dimension (only for 5D+ vectors).

  • m (int) – Index of sixth dimension (only for 6D vectors).

  • element (type) – Value to set at the provided index.

public type[][][][][][] get()

Returns internal array as row-major ordered array - copy of an array is returned.

If you want to update values of original column-major ordered array you have to use one of the methods: set or setElementAt.

Note

The dimension of the returned array depends on the dimension of the vector. The example signature here is for a 6-dimensional vector.

public void set(type[][][][][][] array)

Sets internal array in column-major ordered way.

Parameters:

  • array (type[][][][][][]) – row-major ordered array

Note

The dimension of the array you need to provide depends on the dimension of the vector. The example signature here is for a 6-dimensional vector.
