removing vector entries 1

[jedynygucio]

Hello,
I have a common problem which I have not yet managed to solve. If, for example, I have a matrix A = [1 2 3 4 5 6] and I want to remove the 3rd, 4th and 5th rows, is there a command that will allow me to end up with A = [1 2 6], with the vector reshaped and all the unwanted dimensions removed?
I would appreciate any help on the matter very much, I am sure it is simply a matter of one command.
Best regards,
AJS

In general, elements can be chopped by setting them to []. For example:

A(3:5)=[]
