I need to send multiple commands to a command prompt from MATLAB. But each time when I send a command a new command prompt is opened. How can I send my second command to the same prompt which was opened during the first command. Example: First command: !cmd & next command: !D: &

Use the system() function and string your commands together, separated by semicolons.
system('cmd1; cmd2; cmd3')

If semicolons do not work for you, use ampersands:
system('cmd1 & cmd2 & cmd3')

You have a small number of choices:
  1. Use your loop to construct a character vector or scalar string object that puts all of the commands together and then system() the result; or
  2. (Mac or Linux) system('sh < SomeNamedPipe&') and then have your MATLAB code write to the named pipe; or
  3. (Windows) use System.Diagnostics.Process to construct a .NET connection to a command shell and then write commands to the command shell; see https://www.mathworks.com/matlabcentral/answers/583955-get-the-status-using-system-command-when-program-has-been-closed#answer_485480
