CMatrix:ColsUsed
The ColsUsed method returns the maximum number of column members in any row of the CMatrix.
used = CMatrix:ColsUsed() |
This method returns the number of columns defined in the row having the most number of columns. This is not the same as the maximum index in any row.
Suppose a CMatrix assigned to M contains 5 members as shown below. There are 2 columns defined in row 50:
|
-- create a CMatrix |
|
-- set member |
|
-- set member |
|
-- set member |
|
-- set member |
|
-- set member |
|
-- result: Used = 2 |
|
-- if finished with M, clean up memory |
