remove to only one whitespace in a string

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

ya..I'm required to use function to do this, but your code works for me how should I change if I have to use function to do this?

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

[Orion]

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.
