for i=1:9
N_matrix(1,i)=N(rem(i,3))*ex(i)/3; %(ERROR HERE)
end
Attempted to access N(0); index must be a positive integer or logical.
Error in practisee2 (line 227)
N_matrix(1,i+1)=N(rem(i+1,3))*ex(i+1)/3;

N is a matrix formed from Shape functions. It is related FEM (Finite Element Method) stuff.

Will this expression will result in the same output ..You try....play with values see the output..make a note..change the values....compare the output...remember you are learning..this is the way to learn.

"Will this expression will result in the same output??"
No. Your original expression outputs an error message, whereas my proposed expression will execute.
