Hi Pierre-Aimé,

Thank you for your help!

Hi,

You should use the element-wise multiplication .*instead of the matrix multiplication * in your function f = x * sin(x)
You also had a missing property "color" in the function title
          (and I modified your xdata to be between -5 and 5)

// Close all opened figures and clear workspace
//xdel(winsid());
clear;
clc;

function f=myfunction(x)
f = x.*sin(x)
endfunction

// Plot
scf(1);
clf(1);

xdata = linspace ( -5 , 5 , 100 );
ydata = myfunction ( xdata );
plot ( xdata , ydata );
xlabel("$-5\le x\le 5$","fontsize",4,"color","red");
ylabel("y = x . sin(x)","fontsize",4,"color","red");
title("Function","color", "red","fontsize",4);
legend("Function evaluation");

Best
