Based on the book Computer Vision a Modern Approach page 425, I attempted to use eigenvectors for image segmentation.
I\'m trying to convert a generalized eigenvalue problem into a normal eigenvalue calculation. I have this code:
I\'m looking for a Sparse Matrix library I can use from Ruby. I\'m currently using the GNU Scientific Library bindings provided by the \"gsl\" gem, but my application would be better optimized if I us
I currently have an array of points (x,y) from the result of an A* pathfinding function. This array is set up so that the first index is the point closest to the character and the next one is the next
I\'m trying to generate some axis vectors from parameters commonly used to specify crystallographic unit cells.These parameters consist of the length of the three axes: a,b,c and the angles between th
I hope I manage to explain this clearly. I am trying to calculate the closest point on a circle in 3D. I found the following solution:
I am using umfpack in c++ to solve a sparse matrix. I am having trouble finding wher开发者_运维问答e the [UMFPACK PIVOT TOLERANCE] parameter is set. Would anybody know how to set this control paramete
I am looking for some triangular solvers, and I have come across two solvers. One in BLAS: dtrsmand another in LAPACK: dtrtrs. From the looks of it both seem to have common functionality, with dtrsm h
I apologize for the length of this question and give a pre-emptive thanks for anyone who reads through this!
