Unable to perform assignment because the left and right sides have a different number of elements.

hello,

can anyone tell me why I'm getting this error message in line 16. I'm not very good with MATLAB but I need to solve this O.D.E using Eulers numerical method. Thanks.

clear all;
clc;
k=-0.1865;
te0=0;
Te0=100;
teF=50;
h=0.01;
n=(teF-te0)/h;

te_=[te0:h:teF];
Te_= zeros(n+1,1);
Te_(1)=Te0;

for i=1:n
    fi=k*(Te_(i)-30);
    Te_(i+1)=Te_+h*fi;
end

I would assume this

Te_(i+1)=Te_+h*fi;

was meant to be this

Te_(i+1) = Te_(i) + h * fi;
