◆ MakeHaarMat()

template<class Element >
void MakeHaarMat ( TMatrixT< Element > &  m)

Create an orthonormal (2^n)*(no_cols) Haar (sub)matrix, whose columns are Haar functions.

If no_cols is 0, create the complete matrix with 2^n columns. Example, the complete Haar matrix of the second order is: column 1: [ 1 1 1 1]/2 column 2: [ 1 1 -1 -1]/2 column 3: [ 1 -1 0 0]/sqrt(2) column 4: [ 0 0 1 -1]/sqrt(2) Matrix m is assumed to be zero originally.

◆ MakeHilbertMat() [1/2]

template<class Element >
void MakeHilbertMat ( TMatrixT< Element > &  m)

Make a Hilbert matrix.

Hilb[i,j] = 1/(i+j+1), i,j=0...max-1 (matrix need not be a square one).

◆ MakeHilbertMat() [2/2]

template<class Element >
void MakeHilbertMat ( TMatrixTSym< Element > &  m)

Make a Hilbert matrix.

Hilb[i,j] = 1/(i+j+1), i,j=0...max-1 (matrix must be square).
