How to plot or evaluate the norm of any value?

How do I plot or evaluate the norm of any value?
Especially, I like to plot the norm of the x, y and z component of the magnetic flux density!
Is there a predefined operator, for example norm(mf.Bx) or do I maybe have to self-define such an operator?
I'd be very thankfull if anyone can help me.

Hi

which norm ? w.r.t. complex values ? what else as Bx is a scalar ? or is it the vector norm ? then you must write it out, taking into account if the value is complex

Check help functions to see all available functions, and try Help special operators for more

Good luck

Thomas,

the norm of many vector quantities is readily available, e.g. mf.normB. The norm of any scalar value is the absolute value. So you can use abs(mf.Bx) for example. You find a list of operators in the documentation.

Cheers
