Build and Run Fortran Engine Applications on Windows

This example shows how to build and run the Fortran example fengdemo.F on Windows^® platforms.

Start MATLAB^® as a user with administrator privileges. Based on your User Account Control (UAC) settings, you might need to right-click the MATLAB icon and select Run as administrator. If that option is not available, contact your system administrator.

Register MATLAB as a COM server. For more information, see Register MATLAB as COM Server.

!matlab -regserver

MATLAB displays a second, minimized command window. Close that window.

Make note of the value of matlabroot (the folder where MATLAB is installed). You will use the value res later to set the run-time library path in a set PATH command.

res = fullfile(matlabroot,"bin","win64")

Verify that your current folder is writable and copy the example.

copyfile(fullfile(matlabroot,"extern","examples","eng_mat","fengdemo.F"),".","f")

Choose a compiler, if necessary.

mex -setup -client engine Fortran

Build the application.

mex -v -client engine fengdemo.F

Open a Windows command prompt.

Set the run-time library path by modifying the system PATH variable. Use the value res from the previous step. Make sure that you include the ; path terminator character.

set PATH=matlabroot\bin\arch;%PATH%

Run the example. The fengdemo application must be on your system path.

fengdemo

MATLAB starts and displays a figure.

Type 1 <Enter> at the system prompt to continue and exit.

Alternatively, you can use an integrated development environment (IDE) such as Microsoft^® Visual Studio^® or Xcode to build your application.
