Matrix.MultiplyMV(Single[], Int32, Single[], Int32, Single[], Int32) Method

Definition

Multiplies a 4 element vector by a 4x4 matrix and stores the result in a 4-element column vector.

[Android.Runtime.Register("multiplyMV", "([FI[FI[FI)V", "")]
public static void MultiplyMV (float[]? resultVec, int resultVecOffset, float[]? lhsMat, int lhsMatOffset, float[]? rhsVec, int rhsVecOffset);
[<Android.Runtime.Register("multiplyMV", "([FI[FI[FI)V", "")>]
static member MultiplyMV : single[] * int * single[] * int * single[] * int -> unit

Parameters

resultVec
Single[]

The float array that holds the result vector.

resultVecOffset
Int32

The offset into the result array where the result vector is stored.

lhsMat
Single[]

The float array that holds the left-hand-side matrix.

lhsMatOffset
Int32

The offset into the lhs array where the lhs is stored

rhsVec
Single[]

The float array that holds the right-hand-side vector.

rhsVecOffset
Int32

The offset into the rhs vector where the rhs vector is stored.

Attributes

Exceptions

if resultVec, lhsMat, or rhsVec are null, or if resultVecOffset + 4 > resultVec.length or lhsMatOffset + 16 > lhsMat.length or rhsVecOffset + 4 > rhsVec.length.

Remarks

Multiplies a 4 element vector by a 4x4 matrix and stores the result in a 4-element column vector. In matrix notation: result = lhs x rhs

The same float array may be passed for resultVec, lhsMat, and/or rhsVec. This operation is expected to do the correct thing if the result elements overlap with either of the lhs or rhs elements.
