Hai everyone.. I want to input .txt file or to Fortran .exe file in Matlab.. How could I solve this problem? My .exe file can running in Matlab but I can't input .txt file in Matlab.. For simple ex:
program tes
integer, parameter :: N = 5
real, dimension(1:N) :: x
real :: y
open (unit=1, file='data.txt')
do i = 1,N
read (unit=1, fmt=*) x(i)
y=x(i)+y
end do
close(unit=1)
print*,'y=',y
end program
If I run this .exe file, this program only can run file when I compiled but how do if I want to input other .txt file into this program.. Further, I will make GUI for this program..
Thank you, for your help..

This forum offers the possibility to forma your code. Obviously this would improve the readability of your code very much.

You can try to add uigetfile to your code:
[filename, pathname] = uigetfile('*.txt', 'Pick your text file');
This will launch a selection window where the user can retrieve a .txt of hher/his choosing.

You would also have to copy the user's .txt file into 'data.txt' in the directory you started up the Fortran program from.

If you remove the open and close, and you change the unit number to 5, then the program would be able to read from standard input. For example, your MATLAB routine might code:
[filename, pathname] = uigetfile('*.txt', 'Pick your text file');
fullname = fullfile(pathname, filename);
cmd = ['tes < ', fullname];
system(cmd);

Perhaps you overlooked the part where I wrote "If you remove the open and close, and you change the unit number to 5" ? Those changes would remove any dependence on a particular file name, and would instead have the code read from standard input.
