Ta repozitorij vsebuje implementacijo izbranih algoritmov množenja matrik in je del moje diplomske naloge.

Fast Matrix Multiplication

This repository contains implementation of next fast matrix multiplication algorithms:

• classic matrix multiplication
• Strassen's algorithm (<2, 2, 2>, tensor rank 7)
• Laderman's algorithm (<2, 2, 2>, tensor rank 23)
• Bini's approximative algorithm (<2, 2, 3>, tensor rank 10)
• Schonhage's approximative algorithm (<3, 3, 3>, tensor rank 21)

Algorithms are far from optimized, the main goal was to see the diffenences in time complexitiy.

Instalation and running examples

Clone this repository

git clone [email protected]:matejm/fast-matrix-multiplication.git

Go to root folder of the repository and do the usual compile & run cycle:

mkdir -p build
cd build
cmake ..
make

Run demo of all algorithms or time algorithm execution for different matrix sizes:

./../bin/demo
./../bin/time_multiplication

Testing

Google's testing framework is used. To install it on Ubuntu, run:

sudo apt install libgtest-dev

To test the algorithms, run:

make tests
./../bin/tests
