make replacements in an array
Afficher commentaires plus anciens
i have an array of doubles, A.
A = [0; 0; 1; 1; 0; 1];
I wish to replace all the 1's with 'yes' and the 0's with 'no'. can this be done in order to produce an output B?
B = [no; no; yes; yes; no; yes];

A = [0; 0; 1; 1; 0; 1];
C = {'no', 'yes'}
B = reshape(C(A + 1), [], 1);
But as Matt T. said: Now B is a CELL string, which is not exactly "[no; no; yes; yes; no; yes]", because this is not possible in Matlab.

You can't have a matrix of strings 'yes' and 'no', like you've shown. You can have logicals (true/false), but they will display like 1/0. You can make a cell array of strings. You can make a character array of strings by padding the 'no's with a space ('no '). Or, if you have Statistics Toolbox, you can make a nominal array.
What is your purpose in all of this?

A = randi(3,1,10)
B = nominal(A,{'one','two','three'},1:3)
(if you have Stats TB)
