A.2. CLASS TASK 221
valijkl :
Description:
double[]
A list indexes of the elements from symmetric matrix storage that appers in the weighted
sum.
Obtains Ā in block triplet form.
A.2.30
Task.getbaraidx()
i,j,num = Task.getbaraidx(
idx,
sub,
weights)
Obtains information about an element barA.
Arguments
i :
idx :
j :
num :
sub :
int
Row index of the element at position idx.
long
Position of the element in the vectorized form.
int
Column index of the element at position idx.
long
Number of terms in weighted sum that forms the element.
long[]
A list indexes of the elements from symmetric matrix storage that appers in the weighted
sum.
weights :
Description:
double[]
The weights associated with each term in the weighted sum.
Obtains information about an element in Ā. Since Ā is a sparse matrix of symmetric matrixes
then only the nonzero elements in Ā are stored in order to save space. Now Ā is stored vectorized
form i.e. as one long vector. This function makes it possible to obtain information such as the
row index and the column index of a particular element of the vectorized form of Ā.
Please observe if one element of Ā is inputted multiple times then it may be stored several times
in vectorized form. In that case the element with the highest index is the one that is used.
