Constructors

Signature	Parameters	Description
MVector()		Default constructor. Returns a new MVector object initialized to the zero vector.
MVector(src)	src - MVector, MFloatVector, MPoint or MFloatPoint	Copy constructor. Returns a new MVector object whose x, y and z coordinates are set to the x, y and z coordinates of src.
MVector(seq)	seq - sequence of two or three floats	Returns a new MVector object whose x, y and z coordinates are set to the elements of seq. If the sequence only contains two values z will be set to 0.0.
MVector(x, y, z=0.0)	x - float y - float z - float	Returns a new MVector object with the specified x, y and z coordinates.

Sequence Support

An MVector is treated a sequence of three float values: [x, y, z].

len() returns 3.

Indexing and element assignment are supported.

Deletion, concatenation, repetition and slicing are not supported.

Number Support

Operation	Description
MVector = MVector ^ MVector	New vector which is the cross product of the two vectors.
float = MVector * MVector	Dot product of the two vectors.
MVector = MVector / scalar	New vector whose components are those of the given vector, each divided by scalar, which can be of any type which is convertable to float.
MVector /= scalar	Divides each component of the vector by scalar, which can be of any type which is convertable to float, and returns a new reference to the vector.
MVector = MVector * scalar	New vector whose components are those of the given vector, each multiplied by scalar, which can be of any type which is convertable to float.
MVector = scalar * MVector	New vector whose components are those of the given vector, each multiplied by scalar, which can be of any type which is convertable to float.
MVector *= scalar	Multiplies each component of the vector by scalar, which can be of any type which is convertable to float, and returns a new reference to the vector.
MVector = MVector * MMatrix	New vector resulting from postmultiplying the vector by the matrix.
MVector = MMatrix * MVector	New vector resulting from premultiplying the vector by the matrix.
MVector *= MMatrix	Postmultiplies the vector by the matrix and returns a new reference to the vector.
MVector = MVector + MVector	New vector which is the sum of the two vectors.
MVector += MVector	Adds the second vector to the first and returns a new reference to the first.
MVector = -MVector	New vector which is the negative if the given vector.
MVector = MVector - MVector	New vector which is the difference of the two vectors.
MVector -= MVector	Subtracts the second vector from the first and returns a new reference to the first.

Comparison Support

MVector == MVector	Returns True if each component of the first vector is exactly equal to the corresponding component of the second.
MVector != MVector	Returns False is any component of the first vector is not exactly equal to the corresponding component of the second.

All other comparison operators will raise a TypeError exception.
