If I have a matrix from scale, translate, and rotation transform. I want to split 开发者_高级运维this matrix to two matrix. One is rotation+translation matrix, the other is scale matrix.
I am currently working on a algorithm that needs to find all开发者_运维问答 equal occurrences a an item in a matrix. I decided to use uBLAS matrices from boost. So my problem is:

I\'ve recently began putting together an OpenGL ES 1.1/2.0 2D pipeline from the ground up (iPhone only). This pipeline is intended to be used by engineers with no 3D math experience.
I have to perform some 2D transforms under iOS. I know that you can use the transform property of UIView to apply transforms so I am assuming that somewhere t开发者_开发百科here is some optimized code
