I just recently started experimenting with streamtube, sadly I found that this function does not know how to deal with NaN, exchanging NaN with zero might seem a sound idea from the perspective of a streamline but when the width is given by the divergence, zero will mess up the tubes (so I discovered). Perhaps we can set the width to something else? I haven't looked into that but I am wondering if what suggestions you may have. I tried looking into the file exchange for a nanstreamtube but could not find it. I dont want to spend too much time fixing this so I choose to ask. Rodrigo.

I was considering Project Euler and was happy to discover cody. Having now Project Euler questions too is very welcome. Thank you Doug.

Solutions that use these spoil the fun. I’ve enjoyed doing some of the Cody problems, but I think it’s vital that eval, evalin and assignin are banned. Solutions that use these spoil the fun.

Is there a way to target a range of values within the column? For example instead of returning all those that contain 2 in column 1, returning all those that contain 1, 2, and 3 in column 1? Hi Doug
