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?

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.
Cheers to new learning!
