NaNing correlation matrix values based on variable name
显示 更早的评论
Hi MATLAB experts,
how can I set matrix values to NaN based on their variable name?
For example, I have a correlation matrix, and some of the variable names are john1, john2, john3.., bob1, bob2, bob3.., etc.
How can I implement that every correlation value that is not between two john* variables will be set to NaN?
Thanks!

You forced yourself to write difficult and fragile code by having numbered variables. You should use an array instead, then you would probably be able to do it yourself.

MATLAB experts will advise you to avoid forcing meta-data into variable names, and that your code would be much simpler and more efficient if you put all of your data into one array. If you follow their advice your task will be easy.
