CMatrix:Empty

The Empty method deletes all members of the matrix but does not delete the CMatrix object.

Syntax

CMatrix:Empty()

This deletes all matrix members without deleting the CMatrix object itself. If you delete the CMatrix, the object is set to nil and cannot be used again without creating a new instance using new. By calling Empty, the existing CMatrix can be used to Set new members, and so forth.

Example

The following script sets 3 members in a new CMatrix M, then deletes all members of M:

M = CMatrix:new()	-- create a CMatrix
M:Set( 127, 6000, -63.25 )	-- set member
M:Set( 100, 5, 12.34 )	-- set member
M:Set( 4, 600, -42 )	-- set member
Printf("Members = %d", M:Count())	-- result: Members = 3
M:Empty()	-- empty the matrix
Printf("Members = %d", M:Count())	-- result: Members = 0
