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?

[ali kaya]

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

Hi Ali,

Here is a step by step guide:-

1. Add a Subsystem Block:

• Drag a Subsystem block from Simulink > Ports & Subsystems library into your model.

2. Create Mask for the Subsystem:

• Right-click the Subsystem block, select Mask > Create Mask.
• In Parameters & Dialog tab, add three parameters: x, y, z.
• Set Prompt and Name:
• Prompt: x, Name: x
• Prompt: y, Name: y
• Prompt: z, Name: z
• Click OK.

3. Open the Subsystem:

• Double-click the Subsystem block.
• Delete default lines and blocks.

4. Add Multiplication Blocks:

• Drag three Product blocks from Simulink > Math Operations library into the subsystem.
• Connect inputs and outputs:
• For xyz: Connect first Product block to x, y, z.
• For xzy: Connect second Product block to x, z, y.
• For yzx: Connect third Product block to y, z, x.

5. Add Constant Blocks for Parameters:

• Drag three Constant blocks from Simulink > Sources library into the subsystem.
• Set Constant value:
• For x: Set to x.
• For y: Set to y.
• For z: Set to z.

6. Connect Constant Blocks to Product Blocks:

• Connect Constant block for x to the first input of each Product block.
• Connect Constant block for y to the second input of each Product block.
• Connect Constant block for z to the third input of each Product block.

7. Add a Mux Block:

• Drag a Mux block from Simulink > Signal Routing library into the subsystem.
• Connect outputs of the three Product blocks to the inputs of the Mux block.

8. Connect Mux Block to Subsystem Output:

• Connect the output of the Mux block to the output port of the subsystem.

However, as this question is very basic, and if you are new to Simulink, I think you should take a Simulink Onramp course so that you can do a lot more. https://matlabacademy.mathworks.com/details/simulink-onramp/simulink.
