I'm trying to create a simulink model, where a controller will make a system go to certain coordinates. If the error is sufficiently small, I want to select the next coordinate. The list of coordinates is fairly long, so I stored it in a .mat file (this way, it's also easy to select another set of coordinates). I figured the best (least complex) way to accomplish this is a Matlab Function Block.

However, in such a function block, using

'coordinates=load('myfile')'

is not allowed (which makes sense, who wants to load a file 4096 times per second?), but a MATLAB 'from file' block will only feed a signal in time, not an array of time-independent variables. How can I still accomplish to get an array loaded into my Function Block?
