MATLAB: Extracting first letter from the cell

Question

hello,

I have two cell arrays: nam1 = {'John', 'Adam', 'Emma'} nam2 = {'Doe', 'Willson', 'Brown'}

I want to create one array with initials, like this: init = {'JD', 'AW', EB'}

I tried extracting first letters from each array like this:

if true
  % code
end
ininam1 = cellfun (@(x) x(1),nam1,'un',0)
ininam2 = cellfun (@(x) x(1),nam2,'un',0)

but this already fails (Index exceeds array bounds). Can you help me with this? Also combining these two arrays together?

Thanks in advance!

K.

Hi,

nam1 = {'John', 'Adam', 'Emma'} ;
nam2 = {'Doe', 'Willson', 'Brown'};

ininam1 = strcat(nam1{1}(1),nam2{1}(1))
