Method Details

init(list1=None, list2=None, list3=None, list4=None)
(Constructor)

Create a new matrix object from initialized values.

Example:

 matrix = Mathutils.Matrix([1,1,1],[0,1,0],[1,0,0])

Parameters:: list1 - A 2d,3d or 4d list.
(type=PyList of int/float); list2 - A 2d,3d or 4d list.
(type=PyList of int/float); list3 - A 2d,3d or 4d list.
(type=PyList of int/float); list4 - A 2d,3d or 4d list.
(type=PyList of int/float)

Returns:

It depends wheter a parameter was passed:

(list1, etc.): Matrix object initialized with the given values;
(): An empty 3 dimensional matrix.

(type=New matrix object.)

determinant()

Return the determinant of a matrix.

Returns:: Return a the determinant of a matrix.
(type=int)

identity()

Set the matrix to the identity matrix.

invert()

Set the matrix to it's inverse.

resize4x4()

Resize the matrix to by 4x4

rotationPart()

Return the 3d submatrix corresponding to the linear term of the embedded affine transformation in 3d. This matrix represents rotation and scale. Note that the (4,4) element of a matrix can be used for uniform scaling, too.

Returns:: Return the 3d matrix for rotation and scale.
(type=Matrix object.)

toEuler()

Return an Euler representation of the rotation matrix.

Returns:: Euler representation of the rotation matrix.
(type=Euler object)

toQuat()

Return a quaternion representation of the rotation matrix

Returns:: Quaternion representation of the rotation matrix
(type=Quaternion object)

translationPart()

Return a the translation part of a 4 row matrix.

Returns:: Return a the translation of a matrix.
(type=Vector object.)

transpose()

Set the matrix to it's transpose.

zero()

Set all matrix values to 0.

Class Variable Details

colsize

The column size of the matrix.

rowsize

The row size of the matrix.
