Finding equation of a plane using three points as well as using noisy data

I am quite new to Matlab and require to find the location of a plane in space. This only needs to be done using three points however how would I use matlab to programme this and find the equation of a plane using noisy data?

Thank You

You'll need more than 3 points then. But unfortunately you forgot to attach them, probably because you did not read the Community Guidelines, thinking you already knew them. Please attach them along with a screenshot (PNG image) of them plotted with plot3

If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:

You can use planarFit() in this FEX download
