WebColumn-major layout. Actual organization in memory. Note that a 2D matrix is stored as a 1D array in memory in both the layouts. Some languages like FORTRAN follow the column-major layout. Addressing. In row-major layout, element(x,y) can be addressed as: x*width + y. In the above example, the width of the matrix is 4. WebOpenGL assumes colum major matrices; DirectX assumes row major matrices. This means that the translation, in a matrix seen as a float array, will always go in elements at index 12, 13 and 14 in a matrix in memory (where index is in the range 0..15), be it OpenGL or DirectX.

Matrix representation is a method used by a computer language to store matrices of more than one dimension in memory. Fortran and C use different schemes for their native arrays. Fortran uses "Column Major", in which all the elements for a given column are stored contiguously in memory. C uses "Row Major", which stores all the elements for a given row contiguously in memory.
