I remember a problem similar to the one you describe when using a dot product both to substitute for a fast loop and for its normal mathematical purpose, in the same operation: points = np.array([[0, 0, 0], [1, 0, 0], [1, 1, 0], [0, 1,

> numpy also treat them [vectors] as 1xN matrices I may be misunderstanding something, but in numpy at least a vector, a 1×N array ("row vector"), and a N×1 array ("column vector") behave differently. vec = numpy.

The quiz asks for a range that will include the correct answer 9/10 times. Not a point estimate. If you don't have the relevant trivia in your head, broaden the range proportionally. I think the intended point is that we're

The point of being able to run ten-year-old code is the ability to replay an analysis (exact replication). This allows an analysis to be verified after the fact, which increases trust and helps figure out what happened when contradictions

If we relax the restriction that the columns of the 3x3 transformation matrix must be unit vectors, we also get the ability to apply scaling and shear transformations. In solid mechanics, this is called the F tensor, and is used to describ

Requiring replication work for a PhD seems like a great idea. PhD programs already use a mandatory exercise—the qualifying exam—to check a student's competence, with ambiguous effectiveness. Turning the qualifying exam into a replica
