How to add exponential to a simulink model?

Hello!

I have searched everywhere but I cannot find the answer. Let's say I have an equation of x^(2/3). How can I put the ^(2/3)? That is an exponential, but all I can find about exponentials are the exponential of the natural e, like e^x.

Use the Math Function block, select pow as the function. Top input is x, the bottom input is a constant 2/3.

Okay, but where do I insert the parameter 2/3? There is no textbox where I can insert the parameter on the block's properties?

[Paul]

Sorry about that. See my edited answer. After you select the pow function, the block will have two inputs. The top input is x and the bottom input is 2/3.

Thank you very much Paul!
