MATLAB: What is wrong with the code

Question

I want to remove the vowels and I am doing something wrong.

chr = 'The fast black dog'
for i = 1:length(chr)
if chr(i) == 'a'
chr = erase(chr(i),'a')
elseif chr(i) == 'e'
chr = erase(chr(i),'e')
elseif chr(i) == 'i'
chr = erase(chr(i),'i')
elseif chr(i) == 'o'
chr = erase(chr(i),'o')
elseif chr(i) == 'u'
chr = erase(chr(i),'u')
end
end

Answer 1

chr = 'The fast black dog';
match = ["a","e","i","o","u"];
newchr = erase(chr,match)

Best wishes

Torsten.
