A matrix over a finite field.
The Data
field is a pointer to the matrix elements, organized as an array of rows. Note that the size of a row (RowSize
field) is different from the number of columns because more than one mark can be packed into a byte, and rows are always padded to a multiple of sizeof(long). Both Nor and Noc may be zero. In this case, Data ist still a valid pointer, but the memory block it points to has size zero. The pivot table is optional and can be NULL. Besides the marks, each matrix carries the field order, the number of rows and the number of columns. There is no global field order or row length as at the kernel layer.
