In order to use the ADiMat Server via the automatic differentiation routines admDiffFor, admDiffRev, and admHessian and so on, your local ADiMat installation must be properly set up to use this server. This means, you have to register with the ADiMat Server, to configure ADiMat to use this server, and to configure ADiMat to pass your credentials to the server. This is explained below in detail.

Register with the ADiMat Server

Please register with the ADiMat Server using the user registration form, providing your email address, and set a password.

Configure the ADiMat Server URL

Set up the adimat-client program to use the transformation server URL, by either:

• setting the environment variable ADIMAT_SERVER

  • using your OS utilities to set the environment variable ADIMAT_SERVER=https://adimat.de/adimat/transform/, or

  • in your MATLAB startup.m file, by adding the line

    setenv ADIMAT_SERVER https://adimat.de/adimat/transform/

• or in the client configuration file, by adding the line

  server https://adimat.de/adimat/transform/

Configure authentication credentials

The authentication credentials must be passed to the ADiMat Server via the adimat-client program. This can be achieved by either:

• adding the line

  cgi-param auth=authtoken

  to the client configuration file, where the authentication token can be created at the Auth Token page after logging in to this site, or by

• adding the line

  cgi-param auth=username:password

  to the client configuration file.

• adding the command line option

  --cgi-param auth=authtoken, or --cgi-param auth=username:password,

  to the field flags of admOptions, for example

  opts = admOptions(); opts.flags = '--cgi-param auth=authtoken';

  and then using opts with admDiffFor, admDiffRev, and admHessian, for example

  [J r] = admDiffFor(@f, 1, x, opts);
