How can I create a cell array whose elements reflect a length based on a given input vector?
显示 更早的评论
For example, I want to repeat the character 'b' a specified number of times based on a vector; let's say the vector is [3 2 4]. My desired output would be a 1x3 cell array with elements:
{'bbb'} {'bb'} {'bbbb'}
Ideally, I'd like to implement this without a loop. I'm sure there's some nifty Matlab function that accomplishes this, but I haven't been able to find it. repmat and repelem don't appear to be relevant for this particular application (unless I'm using them incorrectly).
Thank you.

Members, how can avoid this for loop?
in=[3 2 4];
result={};
for i=1:length(in)
result{i}=repmat('b',1,in(i));
end

In one line:
>> V = [3,2,4];
>> S = 'b';
>> C = mat2cell(repmat(S,1,sum(V)),1,V);
>> C{:}
ans = bbb
ans = bb
ans = bbbb
