semantics of generating symmetric matrices in numpy

I tried to make a random symmetric matrix to test my program. I don't care about the data at all as long as it is symmetric (sufficient randomness is no concern at all). My first attempt was this: x=np.random.random((100,100)) x+=x.T However,…

For the simplified query: Select t1.c1, t1.c2, t2.d1 FROM table1 t1 LEFT JOIN table2 t2 ON (t1.c1 = t2.d2) It seems from math by the symmetric property that this would be exactly the same as if one reversed the ON to: Select t1.c1, t1.c2,…
