Welcome to ASC-bla’s documentation!#

ASC-bla is a C++ library for basic linear algebra operations. The library provides template classes Vector and Matrix.

Installation#

install it via git-clone:

git clone https://github.com/TUWien-ASC/ASC-bla.git

To configure and build some tests do

cd ASC-bla
mkdir build
cd build
cmake ..
make

Using ASC-bla#

To use ASC-bla in your code, set the compiler include path properly, and include the header files

#include <vector.h>
#include <matrix.h>

All objects are implemented in the namespace ASC_bla. To use them with less typing, you can set

namespace bla = ASC_bla;

or even

using namespace ASC_bla;

You can create vectors and compute with vectors like:

Vector<double> x(5), y(5), z(5);
for (int i = 0; i < x.Size(); i++)
   x(i) = i;
y = 5.0
z = x+3*y;
cout << "z = " << z << endl;

For matrices you can choose between row-major (RowMajor) or column-major (ColMajor) storage, default is row-major.

Matrix<double,RowMajor> m1(5,3), m2(3,3);
for (int i = 0; i < m1.Height(); i++)
  for (int j = 0; j < m1.Width(); j++)
    m1(i,j) = i+j;
m2 = 3.7;
Matrix product = m1 * m2;

You can extract a row or a column from a matrix:

Vector col1 = product.Col(1);
