Simulink button for a cubic function

Trying to solve a nonlinear model and a linearized model using Simulink and I need a simple cubed button. Cannot find it anywhere. Just need something to simply do u^3.

You can use "user defined function" blocks in Simulink for these purposes. Use "Fcn","Matlab function" etc for this For example a matlab fucntion to cube is given

function y = fcn(u)
%........
 y = u^3;

this u....u1..un..... is your arguments and y1...yn are return values...like this you can create any complex function using this block.
