The MATLAB code is {imwrite(red, datestr(now,'yyyy-mm-dd HH-MM-SS-FFF'),'png');}
I want to make file name "test_yyyy-mm-dd HH-MM-SS-FFF".png
Please, Let me know the method.
Thanks.

filename = strcat(datestr(now,'yyyy-mm-dd HH-MM-SS-FFF'),'.png');
imwrite(red, filename);
Solved? Problem was with the syntax for imwrite :-)
Edit 1:
filename = strcat('Test_',datestr(now,'yyyy-mm-dd HH-MM-SS-FFF'),'.png');
imwrite(red, filename);
Now?

@Junwon Park: using sprintf is often clearer than concatenating strings:
filename = sprintf('Test_%s.png',datestr(now,'yyyy-mm-dd HH-MM-SS-FFF'));
