For-loops

The simple MATLAB command

x=0:2:10;

can be coded alternatively using a for-loop as

for jj=1:6,
  x(jj)=2*(jj-1);
end

For-loops can be nested, e.g.

n=5;
for ii=1:n 
   for jj=1:n 
     a(ii,jj)=ii+jj-1; 
   end 
 end

A for-loop that prints out the identity matrices of order n, where n runs from 1 to 4.

n=4;
for jj=1:n
  a=eye(jj)
end
