How can I find implement fzero in Simulink?

In Matlab I have a simple code where I use the fzero function to find a zero of a second order poly. Now I want to simulate this in Simulink, but I can't use the fzero function in Simulink (it doesn't let me assign a anonymous function in the function block).

Can someone tell me what the best wat is to use this functionality in Simulink?

Hi,

You can use an Interpreted MATLAB Function block in your model.

Here, I'm solving sin(x) = 0 with an initial search value of 3.

In case the "interpreted Matlab Fcn" block has to go insight a mask, the simulink diagnostic viewer reports an error of an undefiened function, while the same error does not show up if the block is used in a nested mask. Do you please have a solution to this issue?
