order. That is, the matrix is stored as follows"(See the msdn glloadmatrixf API description) The storage sequence illustrates how matrices in linear algebra are stored in linear memory arrays. d3d stores each row in an array by row, while OpenGL stores each column in each row of the array:The same matrix of Linear Algebra has different storage sequence in d3d and OGL.Line generation: A11, A12, A13, A14 d3d

vectors.In fact, matrix A [m * n] can be regarded as A row matrix consisting of m n-dimensional row vectors, or A column matrix consisting of n m-dimensional column vectors.X [n * 1]/X' [m * 1] is equivalent to one column vector in n/m dimensions. X [1 * n]/X' [1 * m] is equivalent to a row vector in n/m dimensions.Row matri
