function that gives the number of letters in a word

for example abcd should be equal 4 when i define a vector w={'abcd','ccb'} length(w(1,1)) gives me 1 and not 4

Answer 1

[Andrei Bobrov]

length(w{1}) ;

out = cellfun('length',w);

[Jan]

w(1,1) is : {'abcd'}, a {1x1} cell and therefore its length is 1. But you want the contents of this cell element, and therefore nedd the curly braces, as Andrei has shown.
