Resultant of a vector

"To effect" means "to make happen", so that would be saying that the vector makes the values happen, which is not idioamtic; it is rather nonsensical. There are several possibilities.

• values randomly changed by an operator ("operator updated values" does not sound as if it were well defined)
• values randomly modified by an operator
• values randomly conditioned by an operator
• values randomly affected by an operator

"Affected" would be the right term; however, the compound "operator affected values" does not appear to be idiomatic; there would have to be a definition in the text of what that means.
