Undefined function or variable t1

clc;

t=0:0.001:2*pi;
M1=2e6;
M2=2e9;
M=M2;

for i=1:length(t)

      v(i)=2*sin(w*t(i));

      if v(i)==1.5

          t1=t(i);
      end

      if v(i)==-1.5

          t3=t(i);
      end
  end

 t=0:0.001:2*pi;

I doubt that the error message stems from the part of code you posted.
