This option specifies which value will be output when shrinked.
Option list:
- 0: KeepFirstCell :
- Keep the first cell in the shrinked sub-range of the cell.
- 1: KeepLastCell:
- Keep the last cell in the shrinked sub-range of the cell.
- 2: Average:
- Output the average from the shrinked sub-range of the cell.
- 3: Sum:
- Output the sum from the shrinked sub-range of the cell.
- 4:Max
- Output the maximum value fom the shrinked sub-range of the cell.

- 6:SD
- Output the standard deviation from the shrinked sub-range of the cell.

| Pad Method
|
pad
|
Input
int
|
1
|
Specifies the method to pad the Matrix.
Option list:
- 0=const:Constant
- Specifies a constant to pad matrix
- 1=rep:Replicate
- Replicate first left/right column or top/bottom row to pad matrix.
For example, specifies top pad rows=3, that means inserting three rows in the top of matrix and their value is the same as the first top row of source matrix.
- 2=sym:Symmetric
- Use the specified number of the left/right columns or top/bottom rows to pad the matrix in a symmetrical manner.
For example, specifies top pad rows=3, that means inserting three rows in the top of matrix and their value symmetric with the first three rows of the source matrix.
- 3=cir:Circular
- Use the specified number of the left/right columns or top/bottom rows to pad the matrix in a circular manner.
For example, specifies top pad rows=3, that means inserting three rows in the top of matrix and their value is the same as the first bottom rows of source matrix.
- 4=refl:Reflect
- Use the specified number of the left/right columns or top/bottom rows to pad the matrix in a reflect manner.
For example, specifies top pad rows=3, that means inserting three rows in the top of matrix, and take the first row as the midline reflecting 2 to 4 rows of source matrix.
|
| Col Factor
|
cols
|
Input
int
|
2
|
- When Resize Option is Expand option=0, specifies a factor to increase the number of columns.
For example, if Col Factor is 2, the number of columns in the output matrix will be twice the number of columns in the input matrix.
- When Resize Option is Shrink option=1, specifies a factor to reduce the number of columns.
For example, if Col Factor is 2, every two columns in the input matrix will be shrinked into one column.
|
| Row Factor
|
rows
|
Input
int
|
2
|
- When Resize Option is Expand option=0, specifies a factor to increase the number of rows.
For example, if Row Factor is 2, the number of rows in the output matrix will be twice the number of rows in the input matrix.
- When Resize Option is Shrink option=1, specifies a factor to reduce the number of rows.
For example, if Row Factor is 2, every two rows in the input matrix will be shrinked into one row.
