For systems using digital signal processing, developers may use a math workbench such as Scilab / Scicos, MATLAB / Simulink, EICASLAB, MathCad, or Mathematica to simulate the mathematics.
Creators may use a math tool box such as Scilab / Scicos, MATLAB / Simulink, EICASLAB, MathCad, or Mathematica to mimic math for devices using digital signal sort out.
