Hi all,

I'm using Database Toolbox to query data from a PostgreSQL via MATLAB script. I want to do the same from within Simulink. Could anyone help me with that?

Thank you,

You can always use the "MATLAB Function" block. Keep in mind that it is executed at every simulation step.

MATLAB function blocks are giving an error for the 'database' function that code cannot be generated. I got around this by using a MATLAB Level-2 S-function.
