Constructor Detail

ICRS

public ICRS(DataType data,
            int m,
            int n,
            int nz)

Base constructor, creates a matrix with the given nonzero data and increment arrays zeroed out.

Parameters:

data - Where to store matrix data.

m - Number of rows in matrix.

n - Number of columns in matrix.

nz - Number of nonzeroes in matrix.

ICRS

public ICRS(CRS<DataType> toCopy)

Takes a CRS type matrix, copies and transforms it into ICRS.

Parameters:

toCopy - The matrix to copy.

ICRS

public ICRS(TS<DataType> toCopy)

Takes a TS type matrix, and copies it into ICRS format. Warning: sorts the TS matrix to CRS form first!

Parameters:

toCopy - The matrix to copy.

ICRS

public ICRS(TS<DataType> toCopy,
            int m,
            int n,
            int lo,
            int hi)

Takes a TS type matrix, and partially copies it into ICRS. Warning: sorts the TS matrix to CRS form first!

Parameters:

toCopy - The matrix to copy.

m - Number of rows in the resulting matrix (can differ from toCopy if it is in local view)

n - Number of columns in the resulting matrix (can differ from toCopy if it is in local view)

lo - Lower bound of the index from the TS to copy.

hi - Upper bound on the indices (exclusive).

ICRS

protected ICRS(ICRS<DataType> toCopy)

Deep copy constructor.
