double* matAdd (  double *    A,
const double *    B
) 
 

Cheap-o matrix addition; adds two 4x4 matrices to each other; actually only the top left 3x3 matrices are added. The result, A+B is stored in the first matrix

Parameters:
A  matrix
B  matrix
Returns:
the result of the addition, A

double* matMult (  double *    A,
const double *    B
) 
 

Cheap-o matrix multiplication; multiplies two 4x4 matrices with each other; actually only the top left 3x3 matrices are multiplied. The result, AB is stored in the first matrix

Parameters:
A  matrix
B  matrix
Returns:
the result of the multiplication, A

double* tilde (  double *    A,
const anoid::simple::Vector    v
) 
 

Does the tilde operator of a vector and stores the result in the provided matrix. The result matrix is a 4x4 matrix

Parameters:
A  the matrix in which to store the result
v  the vector to "tilde"
Returns:
the tilded vector, A

double* transpose (  double *    A ) 
 

Transposes the upper left 3x3 matrix of a 4x4 matrix and returns the matrix in A

Parameters:
A  the matrix to transpose
Returns:
the transposed matrix, A
