You can use the Interpreted MATLAB function block for this; it can be found under the User defined functions category in the Simulink library browser.

Open your simulink library
1) Select simulink in the tree view. 2) Simulink/user-defined functions/MATLAB Function 3) open a new model and place MATLAB function block in it,then double click on it 4) now write your function
function y = fcn(x)
%#codegen
y = x^2;

I got these error
Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks. Use 'mex -setup' to select a supported C-compiler.

then take this line out: %#codegen It is meant for mex to generate c code for it. Apparently you don't have mex but that's fine.

Use the Interpreted MAT-LAB function block .... MATLAB function: TestFun(u) and it will call m file: TestFun.m
function kp = TestFun(i) kp = i*10; disp(kp); end
