How can I convert a matrix to string with arrayfun?

I have problems converting this array H=[3 5 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1] 1x26 to string which shows counts of a,b,c,d,e .... in a string e.g

3 means 3 a, 5 means 5 b, 1 means 1 z ... So how can I get this string t='aaabbbbbz' from that array ? Thanks in advance.
