Concatenate cells containing strings

49 views (last 30 days)
I need to concatenate cells to obtain new strings within a new cell array.
For example I have cells A and B
A={'hello', 'hi', 'goodbye'};
B={' how are you', ' see you later'};
and want to obtain
message =
2×1 cell array
{'hello how are you' }
{'goodbye see you later'}
I manage to do this using loops
index=[1 3];
for i=1:length(index)
message{i}=[A{index(i)} B{i}];
Is there a more efficient way to do this? I never manage to figure out how to avoid loops, this is a short example but in reality I have much bigger cells.
Thank you in advance
