I have a 1000x1 array that ranges from 1 to 179.
Any values above 90 in this array I need to do 180 minus any of those values above 90.
I am not sure what I need to do to select those values in the array.
Thanks
Dave :)

See Ch 5 of MATLAB Onramp (Indexing into and Modifying Arrays).
You will also find Ch 12 (Logical arrays) helpful for what you want to do.

Thank you.
That was a great help. Don't think I done it very efficiently but I got where I had to be.
