Hello,
I should write a code about euler method. I have generate the equation but the code show me a "Array indices must be positive integers or logical values Error in modes620_1 (line 6) u(0)=1;" error message. My code is
h=0.1;
c=30;
u=zeros(1:6);
v=zeros(1:6);
u(0)=1;
v(0)=-2;
for n=0:10;
u(n+1)=u(n)+h*v(n);
%v(n+1)=v(n)-((c*h)/3)*v(n)-16*u(n);
end
What should I do to correct this?
Thanks from now.

Array indexes start at one not zero for MATLAB. You cannot index into an array at zero. Just start your array indexing at one instead.
u(1)=1;
v(1)=-2;
