= Matrices multiplication test =

== Description ==

This program is dedicated to compare execution time of multiplication 

of a two square matrices on CPU, on GPU and on CPU with optimisation such as 

matrix B (for which A * B = C is performed) is transposed so multiplication 

is done row by row (not row by column) which speeds up execution on CPU.

The matrices A, B and C are squared matrices containing random floating point 

numbers. 

The programm prints result for each operation and two acceleration coefitients

into a console.

The program is completed via Visual Studio on Windows, but here is presented 

only the sorce code file matrices-multiplication.cu, while executable file

is stored in Release section of the repository.

The program prints two small 3x3 matrix and results from 3 different 

calculations to shou that calculus is correct. 

== Program structure ==

Program source code is stored in a source code file matrices-multiplication.cu,

which contain function

* main - for execution of the program,

* multiplyMatricesCPU - for multiplication of matrices on CPU,

* multiplyMatricesGPU - for multiplication of matrices on GPU,

* transposeMatrix - for generating a transposed matrix,

* multiplyMatricesWithTransposeCPu - for multiplication of first and second

transposed matrix,

* printMatrix - for printing the matrix in console.
