matlabcontrol 4.1.0 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free Mac app was originally developed by Paul Davey. The application lies within Developer Tools, more precisely IDE. We recommend checking the downloaded files with any free antivirus.
From the developer:
matlabcontrol is a Java API that allows for calling MATLAB from Java. You can eval, feval, as well as get and set variables. Interaction can be performed from either inside MATLAB or outside MATLAB.
The basic usage pattern with matlabcontrol is to create a factory, and then to create a proxy. The proxy is used to communicate with MATLAB.
You may want to check out more Mac applications, such as Objective Basic, Pleinpot or PLCEdit, which might be related to matlabcontrol.
