I have two matrices their info shown as the following:
% 1st Matrix info
Name Size Bytes Class Attributes
X 1x3 24 double
% 2nd Matrix info
Name Size Bytes Class Attributes
Y 19830x4 634560 double
How can I apply reshape function to execute a dot product between these matrices ?
Main goal: X and Y must have the same size !!!

Forgetting about the shape for the moment, in order to execute a dot product each argument must have the same number of elements. One of your matrix has 3 elements, the other over 79000.
You can reshape all you want, you'll never be able to perform a dot product between these two matrix.
Rather than asking us to solve an unsolvable problem, why don't you tell us what is the real problem? What is the end goal?

I have no idea what you should do since I have no idea what you're trying to do.
I also have no idea what 'above' refers to. If it refers to the stackoverflow post, in that case both vectors are the same size.
