Extracting a particular row from a 3D matrix

I have a 3D matrix u(151,1001,2001) and I need a particular row extracted from it (let's say (51,1,:) in a form of a vector so I could plot it as a time series.

Is there any way that could be done?

There is a Matlab function for that called squeeze (web) that

returns an array B with the same elements as A, but with all singleton dimensions removed.

when computing

B = squeeze(A)

In your case,

v = squeeze(u(51,1,:));

To convert anything to a column vector, you can use (:) in matlab:

v=u(51,1,:);
v=v(:);

Alternatives to solve this problem are reshape and permute, two functions you will probably need when you proceed with 3D-Matrices.
