MATLAB: Find group of points in an array of points

grouping array value

I have a array x(i,j) where randomly x(i,j) = 1 or x(i,j) = 0. I need to find groups of x(i,j) adjacent to each other with x(i,j) = 1. Please help.

MATLAB: Find the minimum value in each row without using min

Wrong in lots of ways. Rather than explain them all, just study my corrections:

x = rand([4,3])
[rows, columns] = size(x);
for row = 1 : rows;
  theRowMins(row) = inf; % Set to infinity
  for col = 1: columns
    if x(row,col) < theRowMins(row)
      theRowMins(row) = x(row,col);
    end
  end
  fprintf('The min of row %d is %f\n',row,theRowMins(row))
end
% Print to command window:
theRowMins
