Dear all,
I have this code, though, I have previously defined all the variables, it still persist a message:
Not enough input arguments.
Error in Riesgo_C (line 2)
aux1 = V_in(V_in(:,12) == BATT,:);
The function:
function [deltaSOC] = Riesgo_C(V_in,BATT,PV,IRR)
aux1 = V_in(V_in(:,12) == BATT,:);
aux2 = aux1(aux1(:,11) == PV,:);
auxD = aux2(:,[2;4;6;8;10]);
auxI = aux2(:,[1;3;5;7;9]);
p = polyfit(auxI(1,:),auxD(1,:),1);
deltaSOC = polyval(p,IRR);
end

Functions have to be called with arguments actually passed in as they have their own sealed workspace, unlike a script. They know nothing at all about what exists in the calling workspace so you have to call the function as
[deltaSOC] = Riesgo_C(V_in,BATT,PV,IRR);
when you call it in order for it to have the inputs it needs.

Your function requires 4 input arguments. You must have called it with less than 4 input arguments. Please check your code where you call the Riesgo function to make sure that you in fact have 4 input arguments. If you can not find the mistake, then please copy the exact code where you call the function and post it here.

So then please copy and paste the command you are issuing to call it from the command line that produces the error. I think that you probably forgot to include one of the input parameters. You need to have 4.

Not enough input arguments.
Error in mylaplasian (line 6)

You are running a function named mylaplasian which accepts one or more inputs, one of which is named g in the function. But when you run mylaplasian then you are not passing in enough parameters to put anything into the g slot.
You should rewrite your function to do something appropriate when the user calls it with fewer parameters than the maximum. For example,
mytest(10,20)
mytest(30)
mytest()
function mytest(P,Q)
if nargin < 2; Q = -99; end
if nargin < 1
error('You need to pass at least one parameter to this function!');
end
fprintf('Input P was: %g\n', P);
fprintf('Input Q was: %g\n', Q);
end
This code illustrates that you can detect that trailing optional parameters have not been passed in, and in that case you can put in default values if appropriate -- but that when the user has not passed in enough parameters for minimal functionality, that you should generate a meaningful error message to inform the user of what is needed.
