Extract an arbitrary vector from a matrix

Hi!

I have a Matrix X (97, 241) and other Y (97, 241) in reference to Longitude and Latitude.

I want to extract a vector from each one that is a combination of differents Rows and Columns.

This combination is specify by an specific starting point and end, lets say I want to start at (4,8) and end at (81, 25) so I want a vector of latitude and other of longitude that are the points connecting this to inicial and ending point.

Thanks!

idx = 4:81 ;
idy = 8:25 ;
x = X(idx,idy) ;
y = Y(idx,idy) ;
