How in Simulink send one signal from an input to one of several outputs according to a given output number?

Simulink has a "Multi-Port switch" element that can be used to switch one of the inputs to a single output.

It is necessary to solve the inverse problem:

to switch the only input signal to the selected output of 10 possible.

How it is better to implement it?

PS

The option with element "Output Switch" does not work. Error "Invalid connection between message and signal ports"

I believe what you are looking for is analogous to a digital decoder. I do not believe a Simulink block to do this exists, but you can create one using the MATLAB function block.

And this is the code for it:

function [y0, y1, y2, y3, y4, y5, y6, y7, y8, y9] = fcn(select, input)
     y0=0;y1=0;y2=0;y3=0;y4=0;y5=0;y6=0;y7=0;y8=0;y9=0;   
     switch select
         case 0
            y0 = input;
         case 1
            y1 = input;
         case 2
            y2 = input;
         case 3
            y3 = input;
         case 4
            y4 = input;
         case 5
            y5 = input;
         case 6
            y6 = input;
         case 7
            y7 = input;
         case 8
            y8 = input;
         case 9
            y9 = input;
     end
end

Here is a broader discription:

• there are 10 objects, each of which contains a structure variable that must be changed in a loop;
• in a cycle, it can vary from 1 to 10 objects, depending on the sampling condition.
• in the loop, we read the data about the object into the buffer, transform the data in the buffer and must put it back from the buffer into the corresponding object.

It turned out to read into the buffer and convert it. But I don't know how to put it back into the right place from the buffer within the framework of the visual scheme ...

PS

There is a variant of a function with a case-selection and an assignment inside the function, but this is not visual.

I would like to stay within the framework of the scheme with a switching module, if it's possible.

It would be easier to debug if you would share your code/Simulink model.

Thanks, but the scheme itself has not yet been formed ... I'm thinking about it. That's why I can't send the code.

So far, the decoder circuit is visible, but it is necessary to block the signal on the unselected outputs so as not to spoil the data in the memory elements connected to the unselected outputs.

In this regard, the question is: is there an element / settings in matlab that controllably blocks the output?
