Tried the regexp(regexprep) family, still don't know how to get this to work...
I have a cell array of strings, some of which looks like: '.XNY.N'
I simply need to check the cell array, if there is a .N or .M, remove it. Same as in excel you select an array and replace .N and .M with empty.
So in this case '.XNY.N' will be '.XNY'
Anyone knows how to do that? Thanks in advance!

I see, so [] means the consecutive letter. Thank you!

Andrei's answer involved [.] with a period between the brackets. That is one of the ways in which you can code a literal period. Normally in regular expressions, a period is interpreted to mean "any character". You can also use \. to indicate a literal period.

Slightly closer to your original question, and using a different regexp pattern:
regexprep('.XNY.N','\.[MN]','')
