Detailed Description

Dense matrices over \(\mathbb{F}_{2^e}\) represented as slices of matrices over \(\mathbb{F}_2\).

This is one of two fundamental data types of this library, the other being mzed_t. For large matrices ( \(m \times n \times e > L2\)) it is advisable to use this data type because multiplication is faster in this representation. Hence, compared to mzed_t one saves the time to convert betwen representations and - more importantly - memory.

Examples:

tests/test_multiplication.c.

Field Documentation

unsigned int mzd_slice_t::depth

Number of slices *

Note

This value may be greater than finite_field->degree in some situations

const gf2e* mzd_slice_t::finite_field

A finite field \(\mathbb{F}_{2^e}\).

rci_t mzd_slice_t::ncols

Number of columns.

rci_t mzd_slice_t::nrows

Number of rows.

mzd_t* mzd_slice_t::x[16]

mzd_slice_t::x[e][i,j] is the \(e\)-th bit of the entry A[i,j].
