Indexing multidimensional matrices with elements is a vector

I have a multidimensional matrix M and a vector V of indeces that i use in this way:

M(V(1),V(2),V(3),...)

Is there a better way to do that? If V has 100 elements is not a good idea write the code in this way.

Moreover if i have 2 vector of indeces V1 and V2, is there a better way that combine them in a single vector

V=[V1 V2];

and use it as previously.

And finally: if V is not a vector but a Matrix and i would like use it like

M(V(1,1),V(1,2),...,V(2,1),V(2,2),...,...)

can i write something to avoid me to reshape V in a vector form?

Thank you in advance.

V=num2cell(V);
matrix(V{:})

I don't know why it works, but it does. Thank you!
