![]() ![]() ![]() To define a custom function for the current session and use it, use MScript to save it to a file (remember to use the same filename as the function) and then use MFunction, where function_name is the name of your function file.įor some practical real world examples of using MATLink, head over to our examples gallery and also check out the documentation. As an example, we'll define and use the magic function from MATLAB, which is not available in Mathematica: You can also natively call MATLAB functions already on its path using the MFunction command. You can force an overwrite of the existing file with the option "Overwrite" -> True for MScript Trying to define an MScript with the same filename twice in the same MATLink session will throw an error. You can now run the above script anytime, several times within the current session, by evaluating MEvaluate (assuming the value for t has not been cleared) or MEvaluate] (this will work even if t is cleared). As a simple example, we'll define a script called timing.m that does some computations using the two variables mat and mat_tr defined earlier and displays the timing for 1000 trials: They constantly needed to realize what one is better between MATLAB versus. The function MScript makes it easy to do this. MATLAB versus Mathematica is constantly a vital fight for insights understudies. I could in theory produce a complete check-list of each MATLAB facility and each corresponding Mathematica facility, but it would take me several weeks to prepare (I estimate): time that I would never get back and effort which would not put any food on the table. I have tried the 2-norm function as described in Matlab, and also the Normalize function, the latter seems a little better but is still incorrect comparing to the results in the matlab example. Clearly I am doing something incorrectly, this is where I get a little lost. Often one wishes to reuse code found online, either on the MathWorks File Exchange or elsewhere and execute it as a script (i.e., in the base workspace and not as a function). I no-longer answer open-ended questions: it takes too much effort for too little benefit. Trying to normalise Vec, now in mathematica, I am unable to recreate the results obtained in Matlab. You should now be all set to use MATLink! If for some reason it fails, please open a new issue on GitHub. If you reset your Mathematica settings or remove MATLink's init.m in $UserBaseDirectory/ApplicationData/MATLink, then the above option will need to be set again. If you're using a 32 bit MATLAB (such as a student version) with a 64 bit Mathematica, then evaluate the following before using OpenMATLAB for the first time (needs to be done only once) On most Windows systems, you will need administrator rights to do this. Register the default MATLAB version by running regmatlabserver in MATLAB.Add MATLAB's bin\win64 directory ( bin\win32 for 32-bit versions) to the operating system's PATH environment variable.If it does not work out of the box, please try following the instructions below: Although MATLink ships with pre-compiled binaries, depending on your specific setup, it might be necessary to manually change a few settings before you can begin to use MATLink.
