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);

That is not a MATLAB error message. It might be an Octave error message. MATLAB error messages do not mention the value of the invalid subscript.

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.

ex(i / 3); Should be an integer value not a float
So try ex(i)/3

you have to explain what you want to do learn about indexing first

What is the intended meaning of ex(i/3) when i is 1 ?
