I have a problem where I need to remove all numerical characters from a string. I currently have it like this:
message = message(message != '0')
message = message(message != '1')
and so on
I want to condense these into a single statement, but I'm having trouble figuring out how to. How would I go about making this more concise?

Here's one way:
message = 'abc0123456def7890ghi'
message(message >= '0' & message <= '9') = []

message = message(~ismember(message, '0123456789'))
