How can convert binary Numerical Values to Strings?
显示 更早的评论
let's say I Have a Matrix M which contains only binary values of 0 and 1
M = de2bi (0:10)
How can I convert that into a Matrix which is comprised of Strings (e.g. 'black' & 'white', or 'zero' & 'one') instead of the 0's and 1's ?
0 1 0 1
0 0 0 1
0 1 0 0
1 0 0 1
to
black white black white
black black black white
black white black black
white black black white

How about
ca = cell(size(yourMatrix)); % Preallocate cell array
for k = 1 : numel(ca)
if yourMatrix(k)
ca{k} = 'white '; % yourMatrix is 1
else
ca{k} = 'black '; % yourMatrix is 0
end
end

"any way to hide the { }, [ ] and ' ' etc in the resulting Array?"
Those are not actually part of the array in memory, they are just artefacts of the display routine that MATLAB uses. If you want to display the data differently, then you can write your own display routine based on fprintf.

E.g.
>> b = rand(5)<.5 % generate some sample data
b =
5×5 logical array
0 0 0 1 1
0 1 0 1 1
1 1 1 0 0
0 1 0 0 0
1 1 1 1 0
>> s = {'black','white'}; % the strings you want for 0 and 1
>> c = s(b+1)
c =
5×5 cell array
{'black'} {'black'} {'black'} {'white'} {'white'}
{'black'} {'white'} {'black'} {'white'} {'white'}
{'white'} {'white'} {'white'} {'black'} {'black'}
{'black'} {'white'} {'black'} {'black'} {'black'}
{'white'} {'white'} {'white'} {'white'} {'black'}
