How can I matlab from a matrix on matlab? : so I have a matrix:

a = [16 456 22 85 93;11 78 310 62 36;1 66 23 67 405];

Whis is the command to graph the 3rd row of the matrix - the grid of the graph should be set to visable and the x (sample) and Y (value) axis labels should be included.

thank you guys :)
