gt (DataMatrix) - Test DataMatrix objects for greater than

Syntax

T = gt(DMObj1, DMObj2) T = DMObj1 > DMObj2 T = gt(DMObj1, B) T = DMObj1 > B T = gt(B, DMObj1) T = B > DMObj1

Input Arguments

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

Output Arguments

T Logical matrix of the same size as DMObj1 and DMObj2 or DMObj1 and B. It contains logical 1 (true) where elements in the first input are greater than the corresponding element in the second input, and logical 0 (false) otherwise.

Description

T = gt(DMObj1, DMObj2) or the equivalent T = DMObj1 > DMObj2 compares each element in DataMatrix object DMObj1 to the corresponding element in DataMatrix object DMObj2, and returns T, a logical matrix of the same size as DMObj1 and DMObj2, containing logical 1 (true) where elements in DMObj1 are greater than the corresponding element in DMObj2, and logical 0 (false) otherwise. DMObj1 and DMObj2 must have the same size (number of rows and columns), unless one is a scalar (1-by-1 DataMatrix object). DMObj1 and DMObj2 can have different Name properties.

T = gt(DMObj1, B) or the equivalent T = DMObj1 > B compares each element in DataMatrix object DMObj1 to the corresponding element in B, a numeric or logical array, and returns T, a logical matrix of the same size as DMObj1 and B, containing logical 1 (true) where elements in DMObj1 are greater than the corresponding element in B, and logical 0 (false) otherwise. DMObj1 and B must have the same size (number of rows and columns), unless one is a scalar.

T = gt(B, DMObj1) or the equivalent T = B > DMObj1 compares each element in B, a numeric or logical array, to the corresponding element in DataMatrix object DMObj1, and returns T, a logical matrix of the same size as B and DMObj1, containing logical 1 (true) where elements in B are greater than the corresponding element in DMObj1, and logical 0 (false) otherwise. B and DMObj1 must have the same size (number of rows and columns), unless one is a scalar.
