rearrange an equation in simulink

I have the following equation modelled in simulink:

y=D·sin(C·arctan(B·x -E·(B·x - arctan(B·x))))

where x is the input variable and B,C,D and E are constants. So I can obtain the y value for any x input.

Lets say I want the other way around, puting an y value as input and get x value. Is there any easy way to do that? or do I need to do all the math to get x=f(y) and create another model?

Thank you!

I'm not necessarily recommending this, but since you asked you can try an Algegbraic Constraint block.

It worked!

The Algebraic Constraint block did the trick!

Thank you!

No known blocks/methods to pull off such a thing in Simulink. Did you try symbolic math?

[Pablo Sevilla]

Thanks for the suggestion. I've tried to get x=f(y) with the "solve" and "isolate" commands but it seems that matlab couldnt isolate x in this formula.
