I am working with a simulation in simulink of a robot that uses a laserscanner to position it self. The kinematics is made in Simulink and for positioning a Embedded Matlab fcn is called each sample. The Embedded Matlab fcn contains the code for the laser scanner. The the laser scanner needs a map that now is loaded from the workspace using the constant block, with sample time put to 'inf'. The constant block is then conected directly to the Embedded Matlab fcn.
The problem is that the map is a large int8 matrix and slows down the system. It seems as the Embedded Matlab fcn loads the file from the constant block each sample. Can't I somehow make the map a global variable or something so that the Embedded Matlab fcn doesn't load it each time. Or get the Embedded Matlab fcn to work against the Matlab workspace, where the map is located.
Best regards Magnus
