Detailed Description


Tile matrix descriptor

Matrices are stored in a contiguous data chunk containing in order A11, A21, A12, A22 with :

     n1      n2
+----------+---+
|          |   |    With m1 = lm - (lm%mb)
|          |   |         m2 = lm%mb

m1 | A11 |A12| n1 = ln - (lnnb) | | | n2 = lnnb | | | +-------—+—+ m2 | A21 |A22| +-------—+—+
