(vrMatScale) Return M scaled by vector V. If V is a scalar then a vector in which x=v, y=v, z=v will be used.

Parameters

v	The vector or scalar to scale M by.

Any copy(

)

(vrCopy) Returns a copy of a Vector, Matrix, Ray, Sphere, AABBox, Quaternion or Plane

number determinant(

)

(vrMatDeterminant) Returns the determinant of the matrix

number get(	number	x,
	number	y
	)

(vrMatGetValue) Get the value of an element of a matrix.

Parameters

x	The column of the element to select.
y	The row of the element to select.

vrmatrix4 getInverse(

)

(vrMatInverse) Returns the inverse of a 4x4 matrix.

Any getTranspose(

)

(vrMatTranspose) Returns the tranpose of a 3x3 matrix, or a 4x4 matrix with the 3x3 component transposed.

Returns: vrmat3 or vrmat4 depending on the type passed in

Any normalise(

)

(vrNormalise) Returns normalised vector/matrix.

Returns: Normalised vector or matrix depending on the type passed in

Any operator*(

)
