Data may not have more than 2 dimensions.

What is wrong in this articles? Please let me know the solution for this problem.

what do you find if you enter 'doc loglog'?

Check the size of mag and phase:

size(mag)
size(phase)

the bode command will return 3 dimensional array.

To get your loglog command to work try the following:

loglog(w,squeeze(mag),0)

Laterz
