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.
