MATLAB: Removing multiple blanks for a string

blankisspaceMATLABspacestrings

suppose I have a string mystr='Tom and Jerry' I want to write a function that removes all the spaces and leaves just one space in between each word. So I would want the outcome to be 'Tom and Jerry' I used mystr=mystr(~isspace(mystr)) and got TomandJerry but how would I include one space in bettween each word? Thank you

txt_old = 'Tom    and    Jerry';
txt_new = regexprep(txt_old,' +',' ')

See

doc regexprep

for details.

This replaces the hyphen with a space.

You can use the loop if you want. You simply have to tweak it:

n = length(str);
for k = 1:n
    if strfind(str(k),'-')
        str(k) = ' ';
    end
    strOut = str;
end

A simpler implementation eliminates the loop entirely:

The loop is the problem. Just use strfind:

k = strfind(str,'-')
str(k) = ' ';

There are other functions that will do this more effieicntly (that I will let you search out).

MATLAB: Remove to only one whitespace in a string

Hi,

you need to use a regular expression

mystr = 'Lets      go       party';
mystr = regexprep(mystr,'\s+',' ');
% \s+ means multiple spaces
mystr =
Lets go party
