Hi

I have the following three arrays:

A{1}='abc_12341';
A{2}='abc_21313';
A{3}='abc_13511';

Here, I'd like to change abc to def. How can I do this without using "for..."?
I tried this but not wored:

A{:}(1:3)='def';

Thanks!

How about using cellfun:

cellfun(@(x)['def',x(4:end)],A,'un',0)

One approach:

B = regexprep(A,'abc','def')

strrep(A,'abc','def')

or use regular expressions, for instance:

regexprep(A,'^abc','def')
