Count how many ‘a’ are in str and eliminate those ‘a’

so for ex in a str= i have an apple

and we want to see how many a and remove them we would use

str1= 'a'

ind = strfind(str, str1)

str(ind) = ''

how would we use a loop for this?

s = 'I have an apple';
[a,b] = regexp(s,'a','split');
numA = length(b);
sentenceWithoutA = strjoin(a);

okk but in a loop i said

[Daniel M]

Well that seems arbitrary. Silly homework problems. But this technically complies...

for j = 1:1
  [a,b] = regexp(s,'a','split');
  numA = length(b);
  sentenceWithoutA = strjoin(a);
end

Because otherwise it hurts me too much inside to solve such a simple problem in a loop.

@Daniel M: nice loop, made me laugh!

ok reported :)

You would probably get a chuckle out of your teacher if you handed in that loop. Also, flagging is not doing what you think. It does attract the attention of site administrators, but it is more likely flags will be dealt with by high reputation members, so exactly the people whose comments you are flagging.
