Best Answer

in this case
r = {'<=50k' '>50k' '>50k' '>50k'}
[a n n] = unique(r)
k = {0,1}
rnew = k(n)
or
rnew = cellfun(@(x)x-'0',regexprep(r,{'<=50k' ,   '>50k'},{'0','1'}))
on FIR comment: try
rnew = regexprep(r,{'<=50k' ,   '>50k'},{'0','1'})
on Pat comment
r = {'<=50k' '>50k' '>50k' '>50k' 'fg' ''}
rnew = regexprep(r, {'<=50k', '>50k'}, {'0', '1'})
t = ismember(rnew, {'0', '1'})
rnew(t) = cellfun(@(x)x-'0', rnew(t), 'un', 0)
