how can we preallocate a 2d array?
显示 更早的评论
there is a warning in my program, it says that the variable is growing inside a loop. so consider pre allocation for speed

Hi,
I am trying to solve this equation:
q_rad_L(i,j)=(ew./(a_g_p+ew-a_g_p).*ew).*thau.*(e_g_p.*T_ini.^4 -a_g_p.*T_iw.^4).*(a_hat./(x(i)-x(i-1)));
I want to solve to some values: i=1:15, j=1:15 into a loop.
I will appreciate for any response.
Josh
