How do I repeat a character n times?

Freq=[s0,s1,s2,s3,s4,s5,s6,s7,s8,s9];
hist=[1,length(Freq)];
for k=1:length(Freq)
    hist(k)=repmat('*',Freq(k));
end

I want to create a row vector where every element in 'hist' has '*' whose quantity corresponds to the elements from the array 'Freq'. If Freq(5)=6 then hist(5) = '******'

Because your histogram counts will result in variable length strings of asterisks, you'll need to use cell arrays to store each string.

Freq=[s0,s1,s2,s3,s4,s5,s6,s7,s8,s9];
hist=cell(1,length(Freq));
for k=1:length(Freq)
  hist{k}=repmat('*',1,Freq(k));
end

Access the k-th string using hist{k} (note the curly braces).

Thank You! I had tried to use cell array previously but I was enclosing {'*'} rather than k.

You will need to use

hist = strings(1,length(Freq));

and you will need to use R2016b or newer.

R2016a and older cannot store multiple characters in single location that is accessed using () indexing.
