MATLAB: Avoiding nested for loops for matrix assignment

Question

Hi,

I am a beginner to matlab. Can you please tell me how to avoid using nested for loops in matlab.

THis piece of code is taking lot of space in my hard drive and time.

for i = 1:10000
    
    for j = 1:10000
        a(i,j) = i+j
    end
end

Answer 1

m = 10000 ; n = 10000 ;
[i,j] = meshgrid(1:n,1:m) ;
a = i+j ;
