Matrix Input and Output

The example shows the ability of Stateflow® to accept matrix input signals from Simulink® and also output matrix signals to Simulink. In this particular example, we are multiplying a [2x2] matrix with another [2x2] matrix to obtain a [2x2] output matrix. A flow chart is used to perform the calculations which is also the reason why the length of the simulation time is only one timestep.

The graphical flowchart is equivalent to writing the following nested-loop in the C language:

for(i=0; i<2; i++) { for(j=0; j<2; j++) { int final_out[2][2]; final_out[i][j] = (data1[i][0] * data2[0][j]) + (data1[i][1] + data2[1][j]); } }

'final_out' is the Stateflow output signal in this example.
