How to run MATLAB executables on DOS ?

I would like to run an executable on DOS which generates a image file, but seems nothing comes out. The program is as follows :

A = rand(500);
imwrite(A, "Testing.png");

Do you get the results you expect when you run this from explorer? Do you see the splash screen?

Thanks ! I have tried it works now !

And may I ask can MTALAB code be run under Apache Server ?? If it can, then may I ask about the step ??

[ status , cmdout ] = dos( command ) calls the operating system to execute the specified command and returns the output of the DOS command to cmdout .
