hello this is my code and when i run it i get the error index exceed matrix dimension. i cant figure out the error so anyone can help?

[m,n]=size(I0);
M=0.5*ones(4,3);
M(1,2)=0.5*cos(2*0);
M(1,3)=0.5*sin(2*0);
M(2,2)=0.5*cos(2*0.61);  
M(2,3)=0.5*sin(2*0.61);
M(3,2)=0.5*cos(2*1.57);
M(3,3)=0.5*sin(2*1.57);
M(4,2)=0.5*cos(2*2.71);
M(4,3)=0.5*sin(2*2.71);
M=double(M);
%reconstruction surface
S0=zeros(m,n);
S1=zeros(m,n);
S2=zeros(m,n);
S3=zeros(m,n);
disp('calculate stokes')
for i=1:m
    for j=1:n
        I=double([I0(i,j);I35(i,j);I90(i,j);I155(i,j)]);
        S=linsolve(M,I);
        S0(i,j)=S(1,1);
        S1(i,j)=S(2,1);
        S2(i,j)=S(3,1);
    end
end
ro=sqrt(S1.*S1+S2.*S2)./(S0+eps);
AzimuthalAngle=0.5*atan(S2./(S1+eps));  
disp('mask')
MASQUE=OuvreMasque_2011('masque.png',I0) %imread('masque 1629.jpg');
MASQUE=im2bw(MASQUE);
%contourf(ro.*MASQUE);
disp('rho, phi')
ro=min(abs(ro),0.90);
ZenithalAngle=zeros(m,n);
nc=8;
options=optimset('Display','notify');
kc=fsolve(@(t)(2*nc*(1/(1+2*nc+nc^2+t^2)+1/(nc^2+t^2+2*nc+1))-0.37),1,options);
count=m*n;
for i=1:m 
      for j=1:n
      * _if MASQUE(i,j)==1_ *
          ZenithalAngle(i,j)=fsolve(@(t)((nc^2+kc^2-1)*(1-cos(t)^2)/((nc^2+kc^2+1)*(1+cos(t)^2)+4*nc*cos(t))-ro(i,j)),0.5,options);
      end
      count=count-1;
   end
end
