hi all, I am writing a function that to remove the blanks between the words and return it to only one space. like
mystr = 'Lets go party'
Return to
remove_blanks(mystr) = 'Lets go party'
So far, I got mystr = 'Lets go party'; function remove_blanks(mystr) y = mystr(isspace(mystr))='';
I know how to remove all the space between the words but I don't know how to remove to one left.

Hi,
you need to use a regular expression
mystr = 'Lets go party';
mystr = regexprep(mystr,'\s+',' ');
% \s+ means multiple spaces
mystr =
Lets go party

It's not clear what you're asking. regexp is a function.

just do a function :
function cleanstr = remove_blanks(mystr)
cleanstr = regexprep(mystr,'\s+',' ');

A regular expression is the simplest way to do that. Otherwise you can always strsplit the string (which ignores multiple spaces by default) and strjoin it back.
