Convert 3D data to 2D axisymmetric

I have 3D data that I need to convert into a 2D axisymmetric domain. I need to average all the values along a certain theeta so that I end up with data in r and z. What would be the best way to go about it.

Depending on your data, you have a couple of options. I personally recommend the "squeeze" function, but someone else has asked this question as well. See my comments below.

1. This has been asked before (https://www.mathworks.com/matlabcentral/answers/218519-converting-a-3d-data-into-2d) and it will depend on what your data looks like. If your data is a 1x1xn array where n is any real positive number, the squeeze function will get you there.
2. If you are needing to do calculations per individual row, you are going to have to index and use for loops to handle the data. This should be a quick thing if you can get a function built to calculate per row and then just call the function to calculate each row.
