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

A-H is Matrix Multiplication
There is a struct matrix in the top, which is convenient to write questions.
First, matrix multiplication satisfies the combination law, so we can use a rapid power method
The number of times the given matrix chain multiplication expression needs to be calculated. The number of columns in the current matrix is equal to the number of rows in the next matrix. The result is an invalid error.

Preface
The reason for writing this blog is to record the implementation code for matrix transpose and matrix multiplication, for future contingencies. The direct reason is that tonight (2016.09.13) participated in the Baidu 2017 school recruit's written test (C + + post), there is a matrix transpose after the online
