solve a 3 equations and 3 variables for images

Hi,

I am trying to solve a three equation and thre variables for (each pixel) a set of images. I have solved different errors but I do not know what exactly I should do now and would be grateful if you help me.

here is part of the code:

for i=1:rows
    %fprintf('j=', j);

for j=1:columns

%d1 , d2 , d3 are the value of pixels in three images 
d1(i,j)
d2(i,j)
d3(i,j)
A=[H1, H2, H3; G1, G2, G3; F1, F2, F3]; % these are scalar values for example: H1=2648
B=[d1(i,j);d2(i,j);d3(i,j)];

X=inv(A)*B;
x=X(1);
y=X(2);
z=X(3);

R1(i,j)=x;
R2(i,j)=y;
R3(i,j)=z;

end
end

Error:

Error using  * 
MTIMES (*) is not fully supported for integer classes. At least one argument must be scalar.

 X = A\double(B)
