I need to write a program, using loops and functions, that would count numbers of certain letters in a word.
For example if i input a word:'matlabprogram', and i want to count number of a,b,c,d letters in this word the program would say: a=3,b=3,c=0,d=0
Can you please help me?
P.S. sorry for my bad english

a = ('a':'d')'
b = 'matlabprogram'
out1 = [cellstr(a), num2cell(histc(b,a)')]

word='matlabprogram'
Lettre='abcd'
for k=1:numel(Lettre)
m=Lettre(k);
assignin('base',m,sum(ismember(word,m)))
end

Although the OP asked for the names "a", "b", ... this is not a smart idea and I'd definitely avoid suggesting assignin.
