For loop assignment error

Hi all,

I have crated a set of equations assigned to a letter and contains a variable that goes until 14002, to fill a matrix with this computations I am trying the following:

Axz = zeros(14002,4);

for i=1:14002
    
    Axz(:,i) = [dxx,dxx_,dxz,dxz_;dzx,dzx_,dzz,dzz_];
    
end

The problem comes with the followinf Error:

Unable to perform assignment because the size of the left side is 14002-by-1 and the size of the right side is 14002-by-4.

Error in Test (line 51)
    Axz(:,i) = [dxx,dxx_,dxz,dxz_;dzx,dzx_,dzz,dzz_];

How can I set the left side to be 14002 by 4?

Thanks for you help!
