Try this:

format compact;
format short;
% Generate some sample data.
m1 = randi(50, 4,2)
m2 = randi(50, 4,2)
% Find out how many rows we need to randomize.
numberOfRows = size(m1, 1)
% Get a new order for the rows.
newRowOrder = randperm(numberOfRows)
% Apply that order to both arrays.
new_m1 = m1(newRowOrder, :)
new_m2 = m2(newRowOrder, :)

In the command window:

m1 =
  34    20
   5    29
  23    27
  43    49
m2 =
   2    22
  30    36
   4    46
  43     3
numberOfRows =
   4
newRowOrder =
   2     3     1     4
new_m1 =
   5    29
  23    27
  34    20
  43    49
new_m2 =
  30    36
   4    46
   2    22
  43     3
