times (DataMatrix) - Multiply DataMatrix objects

Syntax

DMObjNew = times(DMObj1, DMObj2) DMObjNew = DMObj1 .* DMObj2 DMObjNew = times(DMObj1, B) DMObjNew = DMObj1 .* B DMObjNew = times(B, DMObj1) DMObjNew = B .* DMObj1

Input Arguments

`DMObj1`, `DMObj2`	DataMatrix objects, such as created by `DataMatrix` (object constructor).
`B`	MATLAB numeric or logical array.

Output Arguments

DMObjNew DataMatrix object created by multiplication.

Description

DMObjNew = times(DMObj1, DMObj2) or the equivalent DMObjNew = DMObj1 .* DMObj2 performs an element-by-element multiplication of the DataMatrix objects DMObj1 and DMObj2 and places the results in DMObjNew, another DataMatrix object. DMObj1 and DMObj2 must have the same size (number of rows and columns), unless one is a scalar (1-by-1 DataMatrix object). The size (number of rows and columns), row names, and column names for DMObjNew are the same as DMObj1, unless DMObj1 is a scalar; then they are the same as DMObj2.

DMObjNew = times(DMObj1, B) or the equivalent DMObjNew = DMObj1 .* B performs an element-by-element multiplication of the DataMatrix object DMObj1 and B, a numeric or logical array, and places the results in DMObjNew, another DataMatrix object. DMObj1 and B must have the same size (number of rows and columns), unless B is a scalar. The size (number of rows and columns), row names, and column names for DMObjNew are the same as DMObj1.

DMObjNew = times(B, DMObj1) or the equivalent DMObjNew = B .* DMObj1 performs an element-by-element multiplication of B, a numeric or logical array, and the DataMatrix object DMObj1, and places the results in DMObjNew, another DataMatrix object. DMObj1 and B must have the same size (number of rows and columns), unless B is a scalar. The size (number of rows and columns), row names, and column names for DMObjNew are the same as DMObj1.
