Is there a function/method for counting the number of times a specific character occurs in a string? Say
v = '30.44.532.56';
This is obviously nonesense, but I would like to check how many times the decimal point occurs so that I can reject if used with a function I wrote. This value would be input into GUIDE gui I am creating, so this is why it's in string format.

I suppose this will actually work.
v = '30.44.532.56';
length(strfind(v,'.'))
