Matrix calculation block and computer-implemented method for computer-aided generation of an executable control program

A matrix calculation block for a graphical modeling environment for technical systems, the graphical modeling environment being adapted to execute block diagrams, blocks of the block diagram having input ports and/or output ports, the blocks being connectable through the respective input ports or the respective output ports by signal lines for data transmission, the matrix calculation block comprising:

• at least one input port configured to receive an input matrix signal;
• a calculation definition comprising at least one error condition check;
• at least one output port configured for emitting an output signal, wherein the output signal is a vector signal or a matrix signal;
• and
• an error port configured for emitting an error signal, wherein a value of the error signal indicates an error state of a plurality of predefined error states, the plurality of predefined error states comprising an error-free state, wherein the value of the error signal depends on whether the at least one error condition check is fulfilled or not.
