I am getting some problem in assigning a value to another value

clc;
clear all; 
close all;

w=1;
i=1;
M1=2e6;
M2=2e9;

for t=0:0.0001:2*pi
    v(i)=2*sin(w*t);
    I1(i)=v(i)/M1;
    I2(i)=v(i)/M2;

      if (v(i)>1.5)
          [v(i)/I1(i)]:=[v(i)/I2(i)];
          v(i)=v(i)+0.0001;
          M22(i)=(v(i)/I2(i));

      elseif (v(i)>2)
          v(i)=v(i)-0.0001;
          M22(i)=(v(i)/I2(i));

      elseif (v(i)<-1.5)
          [v(i)/I2(i)]:=[v(i)/I1(i)];
          v(i)=v(i)-0.0001;
          M11(i)=(v(i)/I1(i));

      elseif (v(i)>2)
          v(i)=v(i)+0.0001;
          M11(i)=(v(i)/I1(i));

      else 
          i=i+1;

      end
      M22(i)=M2;
  end

t=0:0.0001:2*pi;

figure;
plot(v,I1);

hold on;
plot(v,I2);

• "problem in assigning a value to another value" &nbsp values are assigned to variables
• [v(i)/I1(i)]:=[v(i)/I2(i)]; doesn't adhere to the Matlab syntax
