## Reverse/inverse a vector

(OP)
Hello everybody, I have a question.

I would like to reverse a vector, I mean transform [1,2,3,4] into [4,3,2,1].

Do you know if there is any function that can do that?

I have to do with many vectors, so it could be tough to do a bucle with each vector.

Thank you

### RE: Reverse/inverse a vector

There are many ways:

fliplr() for a row vector    (or each row of a 2D array)
flipud() for a column vector (or each column of a 2D array)

x(end:-1:1) for the general case of a 1D vector (either row or column)
