How do I preallocate memory in MATLAB

  1. 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


    3. The attempt at a solution

    here is my code

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

    thanks for the help
