Description of options

Coordinates = Name | #Number

Specifies the coordinates matrix to grid.

Set = Number | Width

Specifies whether to define grid cells based on the number desired in each direction or on the size of the grid cell. The default is to set the number of cells.

XN = Number

When Set = Number this specifies the number of grid cells in the x-direction.

YN = Number

When Set = Number and the coordinates are in 2 or 3 dimensions this specifies the number of grid cells in the y-direction.

ZN = Number

When Set = Number and the coordinates are in 3 dimensions this specifies the number of grid cells in the z-direction.

XWidth = Number

When Set = Width this specifies the width of grid cells in the x-direction.

YWidth = Number

When Set = Width and the coordinates are in 2 or 3 dimensions this specifies the width of grid cells in the y-direction.

ZWidth = Number

When Set = Width and the coordinates are in 3 dimensions this specifies the width of grid cells in the z-direction.

OutName = Name

Specifies the name for the output matrix. This name cannot be in use by another matrix already in memory.

Format = Column | Grid

Specifies whether the output should be presented as a grid containing the values or as a column. If Format = Column a coordinates matrix will be created specifying the location of each grid cell.

CrdName = Name

When Format = Column this specifies the name for the output coordinate matrix. This name cannot be in use by another matrix already in memory.

Type = Count | Summary

Specifies whether each output grid cell will contain a count of the points within the cell or a summary of a variable associated with each point.

SumType = Average | Sum

When Format = Summary, this option controls what type of summary is performed on the values associated with each points. Current options are to calculate the mean value or to sum the values.

Data = Name | #Number

When Format = Summary, this option specifies the data matrix containing the variable associated with each data point in the coordinates matrix.

DataCol = Name | #Number

Specifies the column within the matrix specified by the Data parameter that contains the variable to be summarized.
