The error i keep having is : "not enough input arguments",i don't why i keep getting it, it has all the informations it needs. Here is the code :
function [resultat]= gram(T,nom_function,varargin)
if strcmp(nom_function,'poly')
for indiv1=1:length(T)
for indiv2=1:length(T)
if indiv2<=indiv1
Y=T(indiv2,:)
X=T(indiv1,:)
C=varargin{1}
H=varargin{2}
resultat(indiv1,indiv2)= polynome(X,Y,C,H)
end
end
end
end
end
and here is the code for the function polynome :
function [resultat]= polynome(X,Y,C,H)
resultat=((X*Y')+C)^H
end
With the table T, it has the information for X and Y, and then i juste have to add for the indiviual C and H. So in order to make the command i just type : gram(T,polynome,2,2). Please can someone explain to me how to fix it.
PS: this is a partial of the code, but the solution to fix it here will help fix the other parts.

Note: In case if you didn't notice there is already a function named gram() so rename your function.
Final_result = gram(T,'poly',2,2) % right calling of your function
if strcmp(nom_function,'poly')==1 % change your line to this

Thank you for your answer, yes it does work. but i don't understand why,
the command strcmp is made to compare things, so if i make strcmp(nom_function,'poly')
what it shoud do is compare the nom of the function to whatever i write, so i write : gram(T,polynomiale,2,2), it should work because there is the word 'poly' in polynomiale.
second question, why add "==1" in strcmp(nom_function,'poly') ?

Anytime :)
doc strcmp % read it , it returns a logical answer
Plus if my answer works according to what you expect please accept the answer else let know.
