4 Using MWArra y Classes

To construct a sparse logical matrix with no nonzero elements, use the

following:

public static MWLogicalArray newSparse(int rows, int cols,

int nzmax)

To construct a sparse logical matrix from a supplied full matrix, use the

following:

public static MWLogicalArray newSparse(Object data)

To specify what data is assigned to each element, use the following:

public static MWLogicalArray newSparse(int[] rowindex,

int[] colindex, Object data)

To specify the number of rows and columns in the array, use the following:

public static MWLogicalArray newSparse(int[] rowindex,

int[] colindex, Object data, int rows, int cols)

To specify the maximum number of nonzero elements in the array, use the

following:

public static MWLogicalArray newSparse(int[] rowindex,

int[] colindex, Object data, int rows, int cols,

int nzmax)

Input Parameters

data

Data to initialize the array. See the list of valid d ata types below.

rowIndex and colIndex

Arrays of one-based row and column indices

Row and column index arrays are used to construct the sparse array such that

the following holds true, with space allocated for

nzmax nonzeros:

4-96

1 2 ... 167 168 169 170 171 172 173 174 175 176 177 ... 291 292
