how can i overcome this error ?

t = 0:0.0001:0.07;

v0 = input('please Enter the value for v0:');

R = input('please Enter the value for resistance:');

C = input('please Enter the value for capacitacne:');

f = input('please Enter the value for frequency:');

m = length(t);

state = 'on';

for A = 1:m

    switch state 

        case 'on'
    vs(A) = v0 * sin(2*pi*f*t(A));

    vR(A) = vs(A);

    iR = vR(A)/R;

    iC = 2*pi*f*C*v0*cos(2*pi*f*t(A));

    I = iC + iR;

    if I<=0

       state = 'off';

       tA = t(A);

    end

        case 'off'

    vR(A) = v0*sin(2*pi*f*tA)*exp(-(t(A)-tA)/(R * C));

      if vs(A) >= vR(A)

          state = 'on';

      end

    end
end

plot (t,vs,':',t,vR,'k')

 Error:

In the case of 'off', you make an assignment to vR(A) but not to vs(A), but then you attempt to compare vR(A) to the (non-existent) vs(A). You need to decide what value vs(A) should have at that point and make sure the assignment happens.
