Multiple functions working together?
显示 更早的评论
here is my code in a script coding window:
function [n] = n(x)
syms q
[n]=(q^(x/2)-q^(-x/2))/(q^(1/2)-q^(-1/2));
end
function d=d(x)
d=n(x+1)
end
I then save this and go to the command window and type in d(3), which I would like the output to be equal to n(4), but instead I get this:
Index exceeds the number of array elements (1).
Error in sym/subsref (line 870)
R_tilde = builtin('subsref',L_tilde,Idx);
What the heck is going on!!? I'm new to this, help appreciated!

MATLAB is interpreting:
d(3)
as indexing into the third element of ‘d’.
Run:
which d -all
from a script or your Command Window to see if MATLAB can locate the ‘d’ function in the search path (preferably on your user path).
