Set Data to Zero

Command: Edit -> Data -> Set to Zero ->

This command serves to set parts of the data matrix to zero values. The following option are available:

Columns Selected columns will be set to zero. The columns are selected by the object/variable selector. Alternatively a particular column may be set to zero (or any other value) by entering the formula cX=0 in the DataLab calculator (the X in cX stands for the column number, e.g. c4=0 sets column 4 to zero values).
Rows Selected rows will be set to zero. The rows are selected by the object/variable selector. Alternatively a particular row may be set to zero (or any other value) by entering the formula rX=0 in the DataLab calculator (the X in rX stands for the row number, e.g. r4=0 sets row 4 to zero values).
Marked Columns All columns are set to zero values which contain at least one marked cell.
Marked Rows All rows are set to zero values which contain at least one marked cell.
Marked Cells All marked cells of the data matrix are set to zero.
