Eliminating the rows from a matrix

Hello,

I have a matrix of any size (say m*n),

A=[22 23 44 13 12 ...  4
   33 21 33 42 42 ...  3
   21 33 12 43 13 ...  1
   ................... 4]

I want to remove the rows whose last column has value less than 4.

Desired output is

A=[22 23 44 13 12 ...  4
   ................... 4]
