Calling external program using dos incompatibility in 2015?

Hi everyone, I've successfully used dos command to run external program in Matlab 2012b. The command read like this:

dos('"C:\LSDYNA\program\ls-dyna_smp_s_R610_winx64_ifort101.exe" i=Change_VH_2.k &');

Now I met a problem when using the same code in 2015 version. I've checked up and Matlab website said "On Windows platforms, the MATLAB system, dos, and ! commands add the /D flag to the startup of the Windows Command Processor (cmd.exe) program......To preserve the behavior of previous releases, prepend cmd /C to your operating system command. For example, !cmd /C "cd"."

So I changed my code into:

dos('cmd /C "C:\LSDYNA\program\ls-dyna_smp_s_R610_winx64_ifort101.exe" i=Change_VH_2.k &');

But it gives me the same error. Pls anyone could help?

Thanks in advance!

You did not indicate what the error is that you encounter.

[Alex Shao]

There is no error msg on matlab window but rather reflected from the external program directly.

[Walter Roberson]

And what is it about the external program's execution that allows you to figure out that there was an error?

What is the behaviour you expect? What behaviour do you observe instead.

Saying that it gives you "the same error" does not tell me anything about whether it is breaking down complaining about a missing DLL or if it is executing but clearly has the wrong input parameters.

I get the following error on this issue. I tried googling solutions but didn't find anything. Does anyone have a solution??

LSDYNA appears to be a commercial software product; http://www.lstc.com/products/ls-dyna . As such the source is not readily available so we do not know what code is at any of the listed lines, so we do not know what it was attempting to do at the time -- something to do with reading input.

I see that the executable appears to have been compiled with iFort, but it is still possible that it is encountering the same kind of problem as gfortran encountered: see https://www.mathworks.com/matlabcentral/answers/91919-why-does-the-output-of-my-fortran-script-not-show-up-in-the-matlab-command-window-when-i-execute-it#answer_101270
