Generating a continuous function from discrete data

Good morning everyone,

Is there a function tha can generate a continuous function from discrete data?

In particular i have the following. I basically need a way of interpolating this values even when they jump from 179 to -180. I cannot use look up tables because they need strinctly increasing inputs and i cannot use zero or firts order holds because the data is not function of time.

mod(out.alpha, 360)

for that particular case -- it would fail if you went another loop.

For the generalized continuous case, see unwrap(), https://www.mathworks.com/help/matlab/ref/unwrap.html which works in radians.

rad2deg(unwrap(deg2rad(out.alpha)))

Done! Thanks a lot!

Read about interp1. You can interpolate your data.
