Using Class Methods
rowIndex. This method returns an array containing the row index of each
element in the underlying MATLAB array.
The prototype for the
rowIndex method is as follows:
public int[] rowIndex()
Input Parameters
None
Example — Getting the Row Indices of a S parse MWArray
Get the row indices of the elements of the sparse array:
System.out.print("Row indices are: ");
int[] rowidx = A.rowIndex();
for(inti=0;i<5;i++)
System.out.print(rowidx[i] + " ");
System.out.println();
When run, the example displays this output:
Row indices are: 2 1 2 1 2
maximumNonZeros. This method returns the allocated capacity of a
sparse array. If the underlying array is nonsparse, this method returns the
same value as
numberOfElements.
The prototype for the
maximumNonZeros method is as follows:
public int maximumNonZeros()
Input Parameters
None
