Hi all
I have three matrices which obtained from a series of caculations. these matrices are cumulative i.e. values of matrix 2 are equal to ' values of matrix 1 + other values'. also values of matrix 3 are equal to ' values of matrix 2 + other values'. I want to make two matrices including differences between matrices 3 and 2 as well as matrices 2 and 1.It is necessary that all elements of these two matrics are aqual to a single value. How can I write this program? Thanks

1) A,B,C - your matrix
Mx = cat(3,A,B,C);
Out = diff(Mx,1,3);
a = unique(Out);
2) The inverse problem
A - the initial matrix;
b - a scalar, which add to each element of the matrix;
out = bsxfun(@plus,A,b*reshape(0:2,1,1,[]));

'Out' - two matrices including differences between matrices 1 and 2 as well as matrices 2 and 3;
a - value of elements of matrices 'Out'.
