| Description |
This is a very strange bug in randn(). After every seed-reset, the first call to randn() almost invarably produces a postive number. Most of the time this is a benign defect, but sometimes folks seek to make a random sequence of 1s and 0s using randn>0. If you tried to do this, and reset the seed between every call to randn, then you will get a long sequence of ones. Not random! |
