Input Matrix ims

Input

MatrixLayer

<active>

Specifies the input matrix.

Resize Option option

Input

int

2

Specifies the method to resize the Matrix.
Option list:

  • 0=expand:Expand
  • 1=shrink:Shrink
  • 2=interp:Interpolate
    When method is Interpolate, a Interpolate Method = Barycentric is added. Subsequently, two fields -- X Coordinates Matrix and Y Coordinates Matrix, are added to set boundaries.
  • 3=pad:Pad
Shrink Method shrink

Input

int

2

According to the column factor and row factor, define the shrinked sub-range of the cells in the Matrix. For example, if Col Factor is 2 and Row Factor is 2, four cells (from every two columns and every two rows) will be a sub-range .

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.
  • 5: Min
    Output the minimum value from the shrinked sub-range of the cell.
  • 6:SD
    Output the standard deviation from the shrinked sub-range of the cell.
Interpolate Method interp

Input

int

1

Specifies the method to interplate the Matrix.
Option list:

  • 0=nearest:Nearest
    Interpolate using the nearest points.
  • 1=bilinear:Bilinear
    Two dimensional linear interpolation
  • 2=bicubic:Bicubic Convolution
    Two dimensional interpolation using bicubic convolution.
  • 3=spline:Spline
    Two dimensional spline interpolation.
  • 4=biquad:Biquadratic
    Two dimensional quadratic interpolation.
  • 5=lagrange:Bicubic Lagrange
    Two dimensional interpolation using Lagrange polynomials.
  • 6=kriging:Random Kriging
    Interpolates a raster surface from points using Kriging.
  • 7=idw:Inverse Distance Weighted
    Interpolates a raster surface from points using an Inverse Distance Weighted (IDW).
  • 8=barycentric:Barycentric
    Interpolates a raster surface from points using an Barycentric.
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.

Input

MatrixObject

<unassigned>
