fromRotation

fun fromRotation(angle: Double, result: Matrix2? = definedExternally): Matrix2(source)

Creates a rotation matrix.

// Rotate a point 45 degrees counterclockwise.
const p = new Cartesian2(5, 6);
const m = Matrix2.fromRotation(Math.toRadians(45.0));
const rotated = Matrix2.multiplyByVector(m, p, new Cartesian2());

Parameters

angle

The angle, in radians, of the rotation. Positive angles are counterclockwise.

result

The object in which the result will be stored, if undefined a new instance will be created.
