Implementation of BMat16

[Victorin-Brunel]

Here are the additions regarding BMat16 :

• Creation of BMat16
• Various constructors (with a vector register of 256 bits, 4 64 bits uint, or a two-dimensional vector)
• Comparison operators (==, !=, <, >)
• Acces operator to a particular bit at a position (i, j)
• Method to set a bit at a position (i, j)
• A convertor to a two-dimensional array
• Bitwise or operator between two matrices
• Naive transposition
• Optimized transposition with vector instructions
• Optimized matrix multplication
• Optimized matrix multplication using BMat8 matrix multiplication
• Two naive multiplications (one with the acces operator, the other with the array conversion)
• Number of non-zero rows
• Vector of rows
• Identity matrix of size 0 to 16
• Random matrix, and the possibility to specify a size from 1 to 16
• Swap of two matrices
• Display operator
