x = 8e6 + 2e6*rand(1,1000)

x = 1×1000

1.0e+06 * 8.9245 8.9990 8.8056 9.1550 8.7082 8.4802 9.8895 9.1387 8.6755 9.9939 9.5333 8.1495 9.4403 9.7444 8.8806 8.7724 9.7467 8.1353 8.4268 8.4135 8.5413 9.8195 9.3468 8.0006 9.8938 8.5222 8.9490 8.2695 9.4282 8.9224

value = 3e5;
x(x>9e6) = x(x>9e6) + value;
x

x = 1×1000

1.0e+07 * 0.8924 0.8999 0.8806 0.9455 0.8708 0.8480 1.0189 0.9439 0.8675 1.0294 0.9833 0.8149 0.9740 1.0044 0.8881 0.8772 1.0047 0.8135 0.8427 0.8413 0.8541 1.0120 0.9647 0.8001 1.0194 0.8522 0.8949 0.8270 0.9728 0.8922
