I have following code:
figure
NC = 0.79 % May be any value returned from some function.
subplot(3,4,);
imshow(extracted_watermark);
xlabel([attack 'NC='+char(NC)]);
Here Xlabel is giving output like this (NC= )
It shuld give output numeric value of NC like this (NC=0.79).

Try this
NC = 0.79 % May be any value returned from some function.
subplot(3,4,1);
imshow(extracted_watermark);
caption = sprintf('NC=%.2f', NC); % Add in attack if you want
xlabel(caption, 'FontSize', 20); % I have no idea what "attack" is.

xlabel(num2str(NC,'NC=%.2f'))
Dunno what "attack" above represents. If it's a char variable and wanted as part of the string, then include as desired in the format string.

and the section on annotation of graphics for many examples...
