how to store a vector that i got from a for loop ?

i need put all results in the same vector, the vector A only show me the last result in the for loop

for i=1:3
  a=[2+i,i]
  d=[5+2*i, 3*i]
 endfor
A=[a'   d' ]

Hi,

Here is the solution to your loop based script to save all values:

for i=1:3
  a(i, :)=[2+i,i]
  d(i, :)=[5+2*i, 3*i]
end
A=[a'   d' ]

Good luck.

Note: Always preallocate the variable before loop.

@ Sandra: did u accept it?

[Sandra Minerva Gelista López]

i did my code like your answer, but i modified one thing.

for i=1:3
  a(i,:)=[2+i,i]
  d(i,:)=[5+2*i, 3*i]
endfor
A=[a  ; d ]

and its working perfectly. Thank you

endfor is not a valid MATLAB syntax.
