Create and initialize cell array

Question

I am looking for a decent way to create and initialize a cell array with a given value. I can think of the following oneliner

val = 'hello';
dim = [2, 4, 6];
arrayfun(@(x) val, zeros(dim), 'UniformOutput', false)

but I feel dirty.

It means cleaner that my above solution. Yes, clean code is also a vague concept, but still an arguably useful one. — P-Gn

If you want to avoid arrayfun, you could do

C = cell(dim);
C(:) = {val};

or

C = cell(dim);
[C{:}] = deal(val);

A simpler alternative:

C = repmat({val}, dim);
