Please include the part of your code where the error occurs together with the complete error message.

Best wishes

Torsten.

Pass in more arguments.

If you want more meaningful help ask a more meaningful question with details of what you are doing, code and how you are running the code and the exact error message.

At a guess you are probably running a function with the green 'Run' arrow that requires arguments so you need to call it from command line, another function or a script.

@lakom Mariem: See How to ask a good question. Currently all information the readers got are, that you have called any command with too few inputs. Of course the only possible answer is: "Provide more inputs". But this is such obvious, that you should be able to find this answer by your own. And if you want to get a more specific answer, you have to provide any details.

Well, I want to plot the function CLB ,it's expression is the following :

CLB = segma_d - segma_e *(1/2*log(2))

knowing that both segma_d and segma_e are two functions and each one of it have his own expression.

This is my code for CLB function

function ik = Cs_sim(k,alpha,ys,yd,ye)
C=(Segma_d_sim(k,alpha,ys,yd)-Segma_e_sim(k,alpha,ys,yd,ye))/(2*log(2));
if(C<0)
    ik=0 ;
else
    ik=C;
end
end

Fine. And now post a copy of the complete error message to explain, which function is failing. How do you call this function? If you use the green arrow in the editor, no inputs are provide and the computations must fail.

Note that

CLB = segma_d - segma_e *(1/2*log(2))

and

C = (Segma_d_sim(k,alpha,ys,yd) - ...
     Segma_e_sim(k,alpha,ys,yd,ye))/(2*log(2));

are not the same. The latter is:

CLB = (segma_d - segma_e) / 2 / log(2)

The same terms, but due to the different parentheses a completely different result.

It is some work to motivate you to post the required details. In German this is called: pulling someone the worms out of the nose. This can be improved.
