How do I preallocate memory in MATLAB...

animboy

1. The problem statement, all variables and given/known data

I get the error that the variable changes size with each loop iteration then it suggests that I preallocate memory to overcome this. How would I do that?

2. Relevant equations

none

3. The attempt at a solution


here is my code


t=0:0.5:5;
y(1)=1;
for i = 1:10
y(i+1) = y(i)+ (t(i)^2*0.5);
end

thanks for the help
