Subscripted assignment dimension mismatch?

Ex=25; En=3; He=0.1; n=50;
X=zeros(1,n); Y=zeros(1,n);
X(1:n)=normrnd(En,He,1,n);
for i=1:n
   En1=X(1,i);
   X(1,i)=normrnd(Ex,En1,1,n);
   Y(1,i)=exp(-(X(1,i)-Ex)^2/(2*En1^2));
end
plot(X,Y); hold off
??? Subscripted assignment dimension mismatch.

好心人帮帮忙,急用!刚刚学习,马上要用,大家帮帮忙!

解决了

Ex=1; En=0.05; He=0.005; n=20;
X=zeros(1,n); Y=zeros(1,n);
X(1:n)=normrnd(En,He,1,n);
for i=1:n
   En1=X(1,i);
   X(1,i)=normrnd(Ex,En1,1);
   Y(1,i)=exp(-(X(1,i)-Ex)^2/(2*En1^2));
end
plot(X,Y); hold off

X(1,i)=normrnd(Ex,En1,1);多了n
