MATLAB: How to add commas after cell array strings

cell arraycell arrayscommasstrcatstringsstrjoin

Hello,
I'm stuck with one problem for a few hours right now. I want to add commas after my cell array string. Right now it looks like:
a = {'a1','a2','a3','a4','a5','a6'}; a(:)'
ans =
    'a1'    'a2'    'a3'    'a4'    'a5'    'a6'
But I need it to be like this:
    'a1'  ,  'a2'  ,  'a3'  ,  'a4'  ,  'a5'  ,  'a6'
(No comma after last one). I tried a lot of ways, but it seems that I can't create my strings in cell array in form of 'a1', initially. strjoin and strcat doesn't seem to solve this problem as well. I'm kinda lost.

A cell array is by definition a Comma-Separated List. If you want it to appear in your Command Window as one with distinct commas, this works:
a = {'a1','a2','a3','a4','a5','a6'};
fprintf(1, 'a = ')
for k1 = 1:length(a)-1
    fprintf(1, '%s , ', char(a(k1)'))
end
fprintf(1, '%s\n', char(a(end)))
a = a1 , a2 , a3 , a4 , a5 , a6
