let i have a image matrix like : A =
120 200 250 254 225
204 235 226 227 1
243 249 225 29 1
27 82 92 222 224
12 252 229 255 255
I want to change the values within range 240 to 255 into 0 without using for-loop The output array or matrix will be : A =
120 200 0 0 225
204 235 226 227 1
0 0 225 29 1
27 82 92 222 224
12 0 229 0 0
