Is there a开发者_Python百科ny handy library can handle masking operation in Java? Taking care of element by element multiplication, masking boundary elements, etc. Thanks!1) The Java Advanced Imaging
I am working on a C# 2d soft body physics engine and I need to assign masses to an object\'s vertices given: a list of vertices (x,y positions), the total mass for the object, and the center of mass.
I\'m trying to figure out how to use Mathematica to solve systems of equations where some of the variables and coefficients are vectors. A simple example would be something like
I am trying to solve a simple linear equations system using LAPACK. I use dbsvg method which is optimised for banded matrices. I\'ve obsereved a realy strange behaviour. When I fill the AT matrix this
Kindly give me some hint of matrix multiplication using MTL 2. Or any ref. or link for the docum开发者_运维技巧entation of MTL 2.We\'re not supposed to post just links, but here you go. There is a cho
I know the end points of a line segment and the distance/size of the perpendicular end caps I\'d like to create but I need to calcuate the end points of the perpendicular line. I\'ve been banging my h
I\'m working on an iPhone app wi开发者_C百科th some simple animation. I have a view I want to translate, but not along a line. I want to translate it parabolically. Imagine that I am animating a car
For a homework assignment in linear algebra, I have solved the following equation using MATLAB\'s \\ operator (which is the recommended way of doing it):
I saw this question,a开发者_StackOverflow社区nd pop up this idea. Is there an efficient way to do this in PHP?
Suppose we have a m by n matrix A with rank m and a set K⊆{1..n} such that the开发者_运维问答 columns of A indexed by K are linearly independent. Now we want to extend K and find a set L so that k⊆L
