Two applications to set up Analog Computer using operational amplifiers have been shown here using Simscape 2.1 version. The applications solve
i) Simultaneous Equations X+Y=2; 2X+Y=2.5 and
ii) Differential Equation m(d^2x/dt^2)+b(dx/dt)+kx=F(t) with inputs m=2; b=0.7; k=1 and F(t)=0.5.
The results are being displayed in scopes.
