Question: Multiple Orders (DeleteRow + DeleteColumn)

Hello,

can someone help me with the following problem?

Ich want to delete rows and columns at the same time in a matrix. So this I wrote a little proc:

B:=proc(a,b)
DeleteColumn(A,a)
DeleteRow(A,b)
end proc;

The problem is, that only the last order is working. -> 

DeleteRow

Thanks
Martin
