Hi,
I am trying to integrate a function that has constants previously defined in
the same matlab file. Like this:
[J2, ier, nf, err] = quad(@(x) log( ...
sqrt(1 + alpha.^2 + 2.*a.pha.*cos(2.*x)) + alpha + cos(2.*x) ), ...
0, pi/2, 1e-6)
"alpha" is a constant that has been calculated before. However, Octave tells
me "error: alpha undefined ..."
Do I have to write a seperate .m file for each function I want to be able to
integrate? I thought it was possible using the "@(x)" anonymous function
syntax.
I would appreciate any help or pointers to the right documentation. Thank
you!
