Cesium.Matrix4.multiply

Hi,

Using Cesium 1.50 with Chrome 71, I get an error trying to compute:

Cesium.Matrix4.multiply(Cesium.Matrix4.IDENTITY, Cesium.Matrix4.IDENTITY);

message: "Expected result to be typeof object, actual typeof was undefined"
name: "DeveloperError"
stack: "Error
    at new DeveloperError (http://127.0.0.1/cesium/Cesium-1.50/Build/Cesium/Cesium.js:540:19)
    at Object.Check.typeOf.object (http://127.0.0.1/cesium/Cesium-1.50/Build/Cesium/Cesium.js:1866:19)

    at <anonymous>:1:16"

That should not occur, right?

That's a simple case before trying to rotate a 3D model by implementing https://groups.google.com/forum/#!topic/cesium-dev/Yv49L4K2xeo

Thanks,

Hi Dorian,

You are missing the third parameter, result, which is required.
