Hi there could you explain to me that function?

S = num2str(YourBinaryMatrix,'%1d ') is effectively the same as
nrows = size(YourBinaryMatrix,1);
S = cell(nrows,1);
for K = 1 : nrows
S{K} = sprintf('%1d ', YourBinaryMatrix(K,:));
end
S = char(S);
num2str() differs from this in that num2str() figures out the maximum width columns will need to be ahead of time and uses format strings adjusted so that the columns will print out nicely lined up. That lining up is not necessary in the simple case of binary values; it would start coming into play if, for example, you had some values that were single digit numbers and other values that were two digit numbers.

I just want to show the binary values in the command window to show my image is a binary image,like in the command window 0 and 1 will be displayed to illustrate my image is a binary one.

It gives an error "Too many output arguments".
