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
