bessel functions with octave

[john]

Hi,

concerning my question from 16/08/2011, I did the following:



function y=bintegra(q);
global x
y=cos(x*(sin(q)));
endfunction;
when I run the program I got an error  * no conform operator opt1 1x1 opt 2
13x1.
I changed the x with 3 and then it works.

How can I import the x in this function from the begin
input x=3 I used GLOBAL

Thank you
