采纳的回答： Oleg Komarov

I have the following:

test = '''any word'''

which creates a char array containing the word with quotes

now i want to find the position of the quotes:

out = findstr(test,' '' ' )

but this doesn't work and returns an empty array. Can someone please explain how to do this and also why i cant use the escape sequence for single quotes i used to create the word in the first place.

Im using R2008b

Thanks

Matt

在 MATLAB Online 中打开

strfind(test,'''')

With ' '' ' you are looking for < blank>'<blank>
