hello iam new in matlab i have this question: i have ths code to calculate the error between two curves :
function b = fonct(lam)
global Uexp RFexp
%lecture des données expérimentaux
fid =fopen('données expérimentaux.m','r');
M = fscanf(fid,'%e',[1,1]);
xy=fscanf(fid,'%e%e',[2,M]);
xy1=xy';
Uexp=xy1(:,1); %vesteur colonne U2- déplacement
RFexp=xy1(:,2); %vecteur colonne RF2- réaction
mef(lam);
rf4;
Fint=interp1(Uexp,RFexp,-c(:,3),'spline');
b=0;
for i=1:108
X=Fint((i)-RFexp(i)).^2
b=b+X
end
b after runnig it give me this error:
??? Attempted to access Fint(1.99984); index must be a positive integer or logical.
Error in ==> fonct at 16 X=Fint((i)-RFexp(i)).^2 can anyone help me thanks a lot
