Hi,
My objective is to call a matlab function within a fortran code by using the terminal and not Matlab command window. So, I tried to follow this example: https://www.mathworks.com/help/matlab/matlab_external/build-and-run-fortran-engine-applications-on-linux.html
I executed the command
mex -v -client engine fengdemo.F
in terminal. This creates an executable file called fengdemo
I set the library path using the following command format as mentioned here: https://www.mathworks.com/help/matlab/matlab_external/set-run-time-library-path-on-linux-systems.html
LD_LIBRARY_PATH=matlabroot/bin/glnxa64:matlabroot/sys/os/glnxa64:LD_LIBRARY_PATH
export LD_LIBRARY_PATH
PATH=matlabroot/bin:$PATH
export PATH
After I try to execute fengdemo by typing
./fengdemo
However, I have this error:
./fengdemo: error while loading shared libraries: libmx.so: cannot open shared object file: No such file or directory
I checked that glnxa64 is correctly located in matlabroot/sys/os. I don't know why I get these errors.
And finally, I would like to know how the command
gfortran -o binary_fengdemo fengdemo.F
used for fortran programs not including a call to matlab functions can be adapted for fortran programs including matlab calls.

Thank you Suvansh. However, I was aware of those links. I am able to run Fortran and Matlab functions from terminal.
My problem is that fengdemo does not work and I don't know why. I tried to execute a simpler example that is given here: https://www.mathworks.com/matlabcentral/answers/562883-how-do-i-call-use-the-matlab-engine-from-a-fortran-program but I had errors. I would be grateful if you tell me how to solve these errors.
