Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`int`	`blockSize()`	Get the number of rows per block, except last one.
`int`	`blockSize(int bix)`	Get the number of rows of the given block.
`long`	`countNonZeros()`	Compute the number of non-zero values, which potentially makes a full pass over the underlying blocks.
`int`	`countNonZeros(int r)`	Compute the number of non-zero values for the given row, which potentially makes a full pass over the underlying row.
`long`	`countNonZeros(int rl, int ru, int ol, int ou)`	Compute the number of non-zero values, which potentially makes a full pass over the underlying blocks in the row range.
`boolean`	`isContiguous()`	Indicates if the dense block has a single underlying block, i.e., if numBlocks==1.
`boolean`	`isContiguous(int rl, int ru)`	Indicates if the dense block has a single underlying block for the given row range.
`int`	`numBlocks()`	Get the number of allocated blocks.
`int`	`pos(int r)`	Get the position for a given row within its associated block.
`int`	`pos(int[] ix)`	Get the position for a given cell within the associated block.
`int`	`pos(int r, int c)`	Get the position for a given row and column within the associated block.
`void`	`reset(int rlen, int[] odims, double v)`	Resets the dense block by setting the given value.
`DenseBlock`	`set(double v)`	Set the given value for the entire dense block (fill).
`DenseBlock`	`set(int rl, int ru, int cl, int cu, double v)`	Set the given value for an entire index range of the dense block (fill).
`int`	`size(int bix)`	Get the length of the given block.
