Hi, It gives you all values of a that are higher than threshold a>150 gives a logical (0 or 1) matrix from the same size as a: 0 (false) if element < or = 150 ; 1 (true) if element > 150 if you use that as index => you get the values of a larger than 150 greetings

The third line will also print all the gray level values of all pixels to the command window, since he did not end the line with a semicolon.
