1)Direct3D 采用行主序存储 “Effect matrix parameters and HLSL matrix variables can define whether the value is a row-major or column-major matrix; however, the DirectX APIs always treat D3DMATRIX and D3DXMATRIX as row-major.”(见d3d9 document/Casting and Conversion 一节) 2)OpenGL 采用列主序...
其中每一列可被视为列向量，每行可视为行向量。所以不止是column可以被称为vector，row也可以被的。
因为人类习惯的算式是横写的，所以用列表达比较方便。如果用行表达，那整个空间的表达就要变成上下的模式...

前者为填充的数据，后者为表格的表头，也是就列
To convert a row vector into a column vector in Python can be important e.g. to use broadcasting: import numpy as np def colvec(rowvec): v = np.asarray(rowvec) return v.reshape(v.size,1) colvec([1,2,3]) * [[1,2,3], [4,5,6], [7,8,9]] Multiplies the first row ...
In row-major order, the address calculation must find the start of the row and then generate an offset within the row as if it were a vector. Extending the notation that we used to describe the bounds of a vector, we add subscripts to low and high that specify a dimension. Thus, low...
