Re: Integrating a Circular Shaped Loop in a Vector Field

Sir..sorry for not quickly responding,

It is a line integral in the shape of a circle circumference.

I found the below code snippet that uses the trapz function to numerically
integrate a vector:

x=0:pi/357:pi;
y=??????
area=pi/357*trapz(y);

The problem is I do not have a function to integrate..per say.  It is a
vector field of 3 dimensions with only values and no function.

I suppose I could simplify and only integrate the 'z' component?  Maybe
B_field= |Z|*sin (theta)?  That creates another problem because I still need
to vary the circle radius?

Any help is still greatly appreciated.
