API Reference > geometry-core > CartesianGeometry > Matrix3d > applyGivensColumnOp applyGivensColumnOp Method Replace current columns Ui Uj with (cUi - sUj) and (cUj + sUi). This is used in compute intensive inner loops -- there is no checking for i,j being 0,1,2. applyGivensColumnOp(i: number, j: number, c: number, s: number): void Parameter Type Description i number first row index. must be 0,1,2 (unchecked) j number second row index. must be 0,1,2 (unchecked) c number fist coefficient s number second coefficient Returns - void Defined in geometry3d/Matrix3d.ts Line 1042 Last Updated: 12 June, 2024
