how to delete duplicate values in a cell array of characters
显示 更早的评论
hi! I have this cell array of charachter:
a={'1';'1';'1';'1';'1';'3';'3';'3';'3';'3';'3';'4';'4';'4';'4'};
and I want to trasform it in this:
a={'1';'';'';'';'';'3';'';'';'';'';'';'4';'';'';''};
can you help me? thanks

a={'1';'1';'1';'1';'1';'3';'3';'3';'3';'3';'3';'4';'4';'4';'4'};
[~,c,~]=unique(a);
tmp=true(size(a));
tmp(c)=false;
[a{tmp}] = deal('')

this is, of course, one of many solutions

I would have the last line as:
a(tmp) = {''};
I'm sure it involves less work in the background than cell array to comma separated list + deal expansion.

you're right, that's the cleaner way. I often have trouble getting the cell array syntax right...
