MATLAB: How to fill a 3D Array using a for loop

3darrayfor loopmatrix

Hi, I've been having a problem filling a matrix. I need to fill it using a "for" loop, but the equations for each element is different. I hope the example can explain better what I pretend to achieve. Hope someone can help. Thanks.
for i=1:5
  k(i,1,1)=2*x(i);
  k(i,1,2)=9*y(i);
  k(i,2,1)=-2*x(i);
  k(i,2,2)=-2*y(i);
end

Best Answer

x = rand(5,1) ;
y = rand(5,1) ;
k = zeros(2,2,2) ;
for i=1:5
  k(i,1,1)=2*x(i);
  k(i,1,2)=9*y(i);
  k(i,2,1)=-2*x(i);
  k(i,2,2)=-2*y(i);
end
What problem you face? Code is fine.
