Example

The following script removes the row at index n = 100:

M = new_matrix()

-- create a CMatrix object

M:Set( 1, 4, "s1" )

-- set member in row 1

M:Set( 2, 40, "s2" )

-- set member in row 2

M:Set( 2, 18, "s3" )

-- set member in row 2

M:Set( 2, 120, "s4" )

-- set member in row 2

M:Set( 10, 120, "s5" )

-- set member in row 10

Printf("Members = %d", M:Members())

-- result: Members = 5

M:RemoveRow( 2 )

-- remove the row at index 2

Printf("Members = %d", M:Members())

-- result: Members = 2
