I have a code in which I have to use some functions and lists and use them in the body of the code. If I want to type all of them in a file in Mathematica, that file becomes very very long. For example, I have

Func5[x1_,x2_,x3_,x4_,x5_]:=f(x1,x2,x3,x4,x5); ...

List5={...}; ...

the body of my code...

I have to use them these functions and lists in the body of my code. Is it possible to type those functions and lists in a separate file and call them in the body of the code then use them?

  • $\begingroup$ If you have the expressions already in another notebook, then you can just evaluate that notebook using NotebookEvaluate. $\endgroup$

Say you have a notebook called "stuff.nb". In my case, I made one that has a single line:


Now in another notebook (located in the same directory as stuff.nb), evaluate:

NotebookEvaluate[NotebookDirectory[] <> "stuff.nb"]

Everything in stuff.nb is evaluated and so $a$ takes on the value $100$. If you are not in the same directory, then you would need to use the correct path to get to stuff.nb

    $\begingroup$ @mf67 -- Place it in an initialization cell and close the cell. Then it will be executed when you first run something in the new notebook. $\endgroup$
