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

I'm getting the error in the title and not sure how to fix it. My code is below:

%% Analytical Solution
 
% Plot the theoretical 'x' and 'y' displacments of projectile to compare to
% finite difference method.
 
for i = 1:Niter %(From 1 to total number of iterations)
    tSim(i) = (i-1)*dt;
    tNow(i) = tSim(i);
    
    Ax(i) = vx0*tNow;
    Ay(i) = (-0.5*g*(tNow)^2) + (vy0*tNow) + y0;
end 

Thankyou

tNow is a vector, so you can't store it in a scalar, which is what you are trying to do. You probably want to replace every instance of tNow with tNow(i), or replace the entire loop with array operations.

array operations?
