How to run an .exe file and open an input .txt file to that

Hi,

i want to open .exe from matlab and then provide it with input .txt file and then give that program command to RUN the file. I have used this code but it only opens .exe file. how to give it command to open input file and then rut that file into program

FID=fopen('input.txt','wt');     
fprintf(FID,strcat('RP 0 181 1 1000 -90 0 1 1','\n'));
fprintf(FID,strcat('RP 0 1 360 1000 90 01 1','\n'));
fclose(FID)
system('C:\NEC-PRO16\BIN\NECWINP.EXE')

Does the program NECWINP.EXE accepts the .txt file from the command line or through GUI?

[ABDUL MANNAN]

Yes it accepts through command line

[Walter Roberson]

I cannot find a user manual for the program.

The software appears to be more than 20 years old.

[ABDUL MANNAN]

yes you are right it is an old software.

you can find it here https://www.nec2.org/

If it accepts through command line as an input argument then you can try this

system('C:\NEC-PRO16\BIN\NECWINP.EXE input.txt')

and if it accepts it as input text, then you can use redirection

system('C:\NEC-PRO16\BIN\NECWINP.EXE < input.txt')

hi sir, i tried both but its not working. it only opens the .exe file and nothing more

[Ameer Hamza]

Does the program run properly when you run it in Command prompt with input .txt file?

[ABDUL MANNAN]

Yes it runs properly when i run it manually.

You might need to provide the full path to the text file.

[ABDUL MANNAN]

thanks Rik for your reply. i tried this but nothing opens

[Ameer Hamza]

"Yes it runs properly when i run it manually."

How do you run it?

[ABDUL MANNAN]

i mean when i run it manually by opening program and then open this file in the pogram

[Ameer Hamza]

But that does not mean that the program is able to accept the text file from the command line. It might not be supported. You need to check the documentation of the exe program to see if it accept the input arguments from the command line.
