Hello! I am trying to replace multiple words in a string with a single word. For example the sentence would be Hello girl and cat and I want to change it to Hello boy and boy. I've tried to format it as s being Hello girl and cat and then strrep (s, 'girl' 'cat', 'boy')
Thank you!

str='Hello girl and cat'
out=regexprep(str,'girl|cat','boy')
%If you want to use strrep
str='Hello girl and cat'
out=strrep(str,'girl','boy')
out=strrep(out,'cat','boy')

@Azzi Abdelmalek Sir : if i have a string aa='robotic robot'; and if i use bb=strrep(aa,'robot','robotic') then it gives me 'roboticic robot' ; instead i want the output to be 'robotic robotic' . So Sir, how can i be able to achieve it ?

I would use regexprep
aa='robotic robot';
out = regexprep(aa,'robot$','robotic');
