Constructor Detail

MLSparse

public MLSparse(java.lang.String name,
                int[] dims,
                int attributes,
                int nzmax)

Parameters:

name -

dims -

attributes -

nzmax -

Method Detail

allocate

protected void allocate()

Overrides:

allocate in class MLNumericArray<java.lang.Double>

getMaxNZ

public int getMaxNZ()

Gets maximum number of non-zero values

Returns:

getIR

public int[] getIR()

Gets row indices ir points to an integer array of length nzmax containing the row indices of the corresponding elements in pr and pi.

getJC

public int[] getJC()

Gets column indices. jc points to an integer array of length N+1 that contains column index information. For j, in the range 0<=j<=N1, jc[j] is the index in ir and pr (and pi if it exists) of the first nonzero entry in the jth column and jc[j+1]1 index of the last nonzero entry. As a result, jc[N] is also equal to nnz, the number of nonzero entries in the matrix. If nnz is less than nzmax, then more nonzero entries can be inserted in the array without allocating additional storage

Returns:

createArray

public java.lang.Double[] createArray(int m,
                                      int n)
