function f=test(s,c)
f=regexp(find(s=='c'))=[];
end

my s='now is the time for all good'

I am trying to remove all the o's in the sentence. However, when I go to test it I get an error with the second eqal sign --> =[];

it says incorrect use of '=' operator. However, when I try to change it, i still get the same error.

If you absolutely have to use find then you could use

function f=test(s,c)
  idx=find(s==c);
  s(idx)=[];
  f=s;
end

Or, you could simplify it by using regular expressions instead:

function f=test(s,c)
    f= regexprep(s,c,'')
end
