Empty Matrix/Vector

[swopnil123]

Is there a way to create an empty matrix or vector? It would be helpful in the code blocks inside a function to append new elements and return empty if the condition is not met.

Also append is not working with row vector. But seems to work with column vector

Issue is solved.

To create a row vector insert new values by hitting tab not comma. To create an empty vector, don't forget to write =? after [ ]. It will render as [] and works fine.
