Hi,

Does anyone have or know where I can find a Mathcad 15 worksheet that demonstrates an ellipsiod fit to 3D data?

Thankyou in anticipation,

Mike.

Here's a worksheet that shows how to do a parametric fit to an ellipse. It could be adapted to an ellipsoid.

    That is exactly what I was looking for, thankyou very much. Now to decipher it and plug in my own data

    Ok, I've had an attempt at putting in my data and performing a fit, please see the attached. I'm not sure what I'm dong wrong to be honest, I suspect my angles are giving the issue somewhere along the line. I thought I understood the worksheet - obviously not DOH!

    Anyone out there that can offer up any advice (other than give up on Math)?

    Thankyou.
