I have the following inequalities on 21 variables: http://pastebin.com/raw.php?i=FTU970Em When I run \"Reduce[ineq,Integers]\" on this, Mathematica hangs for a
I created a simple test appl开发者_运维知识库ication to perform translation (T) and rotation (R) estimation fromthe essential matrix.
I\'m using XNA but it doesn\'t matter too much for this example. So let\'s say I have a sprite. I then apply a scaling matrix before anything. Is the scaling matrix applied scaling the local axis of t
The following function does not use row pivoting for LU decomposition. Is there an existi开发者_如何学Pythonng function in R that does LU decomposition with row pivot?
I need an algorithm to perform a 2D bisection method for solving a 2x2 non-linear problem. Example: two equations f(x,y)=0 and g(x,y)=0 which I want to solve simultaneously. I am very familiar with th
Assume you have an NxM matrix A of full rank, where M>N. If we denote the columns by C_i (with dimensions Nx1), then we can write the matrix as
How is R able to find eigenvectors for the following matrix? Eigenvalues are 2,2 so eigenvectors require solving solve(matrix(c(0,1,0,0),2,2)) which is singular matrix with no solution.
