 /**
  * Represents an in-place matrix transformation – the matrix/vector operated on is mutated. A
- * MatrixTransformation instance represents an implied transformation matrix (to be premultiplied). Through
- * the {@link Access2D} and {@link Access2D.Collectabl} the elements of that matrix can be access and
- * collected.
+ * MatrixTransformation instance represents an implied transformation matrix (to be used as the input argument
+ * to the {@link PhysicalStore#multiply(org.ojalgo.matrix.store.MatrixStore)} or
+ * {@link PhysicalStore#premultiply(org.ojalgo.access.Access1D)} methods). But, this interface does not
+ * require you to disclose the size and shape of that matrix, nor to be able to explicitly access any of the
+ * individual elements.
