Hi, I would like to know how to get separate cells with chars from number array:

from

 F=[1 20 30 100];

to

 E={'1','20','30','100'};

Answer 1

E = cellfun(@num2str,mat2cell(F,1,ones(1,4)),'UniformOutput',false)

Answer 2

[Honglei Chen]

E = mat2cell(F,1,ones(1,4)])

Answer 3

OK, but i need those E values to be not in [ ], but in ' ', it means in char.
