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

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

thanks...

Change the line

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

R=0
while R<=1000 | R>=2000
  R = input('please Enter the value for resistance:  1000<=R<=2000');
end
