Available Options
Data = Name | #Number
Specifies the data matrix containing the column to fold.
Column = Name | #Number
Specifies the column of the matrix specified by the Data command data to fold.
Name = Name
Specifies the name for the new matrix. This name cannot be in use by another matrix already in memory.
Type = Rect | 3D | Dist | Angle | Binary
Specifies the type of matrix to create from the folded column. Rectangular, 3D (cubic), distance, angle and binary matrices can be created.
The following options apply only when the data is being folded into a rectangular matrix.
Rows = Number
When Type = Rect, specifies the number of rows in the new matrix.
Cols = Number
When Type = Rect, specifies the number of columns in the new matrix.
The following options apply only when the data is being folded into a 3D matrix.
X = Number
When Type = 3D, specifies the size of the matrix in the x-direction.
Y = Number
When Type = 3D, specifies the size of the matrix in the y-direction.
Z = Number
When Type = 3D, specifies the size of the matrix in the z-direction.
The following option applies only when the data is being folded into a distance, angle or binary matrix.
N = Number
When Type = Dist or Type = Angle or Type = Binary, specifies the size of the square output matrix (n × n).
The following options apply only when the data is being folded into a distance or angle matrix.
Shape = Full | Lower | Upper
This parameter specifies whether to fold the entire matrix (Shape = Full), or only the lower or upper triangle. The latter options should be combined with the Diagonal parameter.
Diagonal = Yes | No
When the Shape parameter is Upper or Lower, this parameter specifies whether the diagonal is included in the to-be-folded column.
