popup multiplication combinations for mask

I want to make a mask for different multiplication combinations such as xyz xzy yzx etc.(x y z is a vector) in simulink could you help me?

[Aquatris]

Are x y z signals going into the mask or parameters of the mask? What is the output of the mask?

parameters of mask , output is a vector.

There are a lot of ways to do this and its hard to tell which one would be the best for your application, but here are two:

• If they are parameters of the mask, you can define another parameter of the mask that defines the order, and write a callback for the new parameter to handle the multiplication order. For instance if the new parameter value is [1 2 3] than it would be xyz, if it is [1 3 2] than it would be xzy etc.
• if you have the parameters as constant blocks,you can use bus creator and bus selector to arrange their multiplication order where the 3 bus selector/output signals are promoted in the mask to arrange the order
