multiplyInverseXYZW Method

Multiply matrixInverse * [x,y,z] and return result as a Point4d with the given weight as the last coordinate.

• Equivalent to solving matrix * result = [x,y,z] for an unknown result.
• Result is undefined if the matrix is singular (e.g. has parallel columns or a zero magnitude column)

multiplyInverseXYZW(x: number, y: number, z: number, w: number, result?: Point4d): undefined | Point4d

@returns result as a Point4d with the same weight.

Returns - undefined | Point4d

result as a Point4d with the same weight.
