How to avoid loops
显示 更早的评论
I have an array (3xN, day, longitude, temperature), a vector (10 elements long, TestLongitudes), and a longitude tolerance. I'm attempting to, for each day find the longitudes that are with tolerance of any of the TestLongitudes, and return the mean of the temperatures that meet the criteria. I can write a lot of loops to do the comparisons, but I wonder if there's a better way...
Thanks! Bruce

With respect to comparing the longitudes, the ismembertol function comes quickly to mind. You will have to experiment with it and your data to determine if it’s an appropriate option.
You won’t be avoiding loops, just hiding them. Many of these functions have implicit loops within them.

It can. The functions are optimised, and I believe in many functions, compiled.
My pleasure!
