ex(1)=lx/J      %%first i term in ex matrix
ex(2)=mx/J      %%second j term in ex matrix
ex(3)=nx/J      %%third k term in ex matrix
for i=1:9
    N_matrix(1,i)=N(rem(i,3))*ex(i / 3);(ERROR HERE)
end
Attempted to access ex(0.333333); index must be a positive integer or logical.
Error in practisee2 (line 225)
    N_matrix(1,i)=N(rem(i,3))*ex(i / 3);

First you explain what you intend it to mean. In one of your related posts you said that ex is a function, but it was clear that you had initialized ex as a variable.
