# matrixMulCUBLAS - Matrix Multiplication (CUBLAS)

## Description

This sample implements matrix multiplication from Chapter 3 of the programming guide. To illustrate GPU performance for matrix multiply, this sample also shows how to use the new CUDA 4.0 interface for CUBLAS to demonstrate high-performance performance for matrix multiplication.

## Key Concepts

CUDA Runtime API, Performance Strategies, Linear Algebra, CUBLAS

## Supported SM Architectures
