   Hello. I am fairly new to MATLAB and I am stuck at creating 2 circles with blanks in between the dots(dots will be sensor points): one in x-y and the other in x-z. For x-y I know I can use makeCartCircle. However I cannot come up with anything for the x-z one.

   x-y circle:
   5 -> radius
   40 -> number of points
   [0, 0, 0] -> center point
   2*pi -> arc angle

   x-z circle:
   5 -> radius
   40 -> number of points
   [0, 0, 0] -> center point
   -pi/2, pi/2 -> arc angle

   Follow-up question: Would there be any problems with working this cartesian result into kgrid?
   Thank you in advance.

   Hi johnhop,

   One option is to create both of the circles in 2D using makeCartCircle. Next, create two separate 2D kgrid objects with the correct dimensions (one Nx/Ny, one Nx/Nz). Then convert both Cartesian circles to binary matrices using cart2grid. Finally, you can place these 2D matrices into a larger 3D matrix in the correct plane and orientation.

   Another option is to use makeCartCircle to create both of the circles, create a new matrix with three rows and the total number of points, and then copy the rows to x/y or x/z as appropriate.

   Hope that helps,

   Brad.
