Hi,
small explanation of How I approached the answer. I changed domenstion on B so that it would that of A and the subtracted them both
A = zeros(5,5, 3,2) ;%assumed Dimensions
%value storing
A(:,:,1,1)= 0.67;
A(:,:,2,1)= 0.55;
A(:,:,3,1)= 0.12;
A(:,:,1,2)= 0.12;
A(:,:,2,2)= 0.5;
A(:,:,3,2)= 0.11;
B = [1 ;0];
%get dimenstions of A
[m n o p ] = size(A);
%create two temporary matrices
R1 = B(1)*ones(m,n,o);
R2 = B(2)*ones(m,n,o);
%here multiplication is used to make it versatile for any value of B
%initialize new B
NewB = zeros(m,n,o,p);
NewB(:,:,:,1)= R1;
NewB(:,:,:,2)= R2;
result = A - NewB;
