The decomposition isn't calculated until it is needed. When needed, it is called automatically. You never have to call Decompose explicitly unless you want to control when the decomposition is performed.

Until Decompose is called, either explicitly or implicitly by one of its methods or properties, you can set the Overwrite property to specify whether to overwrite or preserve the original matrix.
