How to fit a helix in 3D using cftool?
18 views (last 30 days)
I am trying to fit some helical data to a helical parametric equation, so as to find the pitch, radius and angle with respect to the z-axis.
If I use the cftool, this is what I am allowed to do in terms of customization (see pic below). There is no option for parametric equations, where the z data can be used as a time variable. Is there any way that this can be done? If not, what functions/tools/methods do you suggest?

Assuming the helical parametric equations to be
“fittype” can be used to assign the model type to fit in order to obtain the parameters a & b.
The same procedure can be used to obtain parameter b as well.
