Graduate Inverse (LS) problem for binary data
My bad. g (and f) are restricted to 0s and 1s. M is matrix with real elements. Well, the data is usually in class of hundreds of elements, so I don't know how much use would cutting do. i.e. basically one 'strip' of the image looks like (g) 0 0 1 1 1 1 0 0 when it...- Zhiv

Graduate Inverse (LS) problem for binary data
Euclidean norm is used at the moment. I have also toyed with amount of non-zero elements. I guess they are pretty much same when the problem is binaric. I just lack mathematical rigour to check this. Well, I'm the lucky situation that f and g are of same rank(?) same size in plain...- Zhiv

Graduate Inverse (LS) problem for binary data
Doesn't change the nature of the problem, as far as I can see. If the matrix has ill inverse (i.e. it exsits but causes numerical problems), I can't see simple algebraic manipulation taking care of it. When it comes to the suggestion of neural networks, that could probably work, but since...- Zhiv

Graduate Inverse (LS) problem for binary data
As per topic. Is there any well established method for solving linear systems for binary data? pardon if this is in wrong cathegory, english is not my first language and I'm not that well aware of the english terms. i.e. the classical g = M*f problem, where g is measured data and we want...- Zhiv

Undergrad Eigenvectors and using them in matrix algebra.
Hi. Marix A= |1 1 0 | |0 2 0 | |2 1-1 | Has three eigenvectors [1,1,1]^T, [1,0,1]^T and [0,0,1]^T, By using this knowledge solve A^11. Ok, solving A^11 is rather easy with any decent calculator, or even with pen , paper and some time, but how on Earth I'm supposed to benefit...- Zhiv
