kandi X-RAY | pyq Summary

pyq is a Python library typically used in Database applications. pyq has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can install using 'pip install pyq' or download it from GitHub, PyPI.

PyQ brings the Python programming language to the kdb+ database. Part of the Fusion for kdb+ interface collection. It allows developers to integrate Python and q codes seamlessly in one application. This is achieved by bringing the Python and q interpreters into the same process so that code written in either of the languages operates on the same data. In PyQ, Python and q objects live in the same memory space and share the same data. Please report issues in this repository.

QUESTION

How to calculate the product of a bunch of exponential functions in the fastest way possible?

Asked 2021-Aug-01 at 07:45

This is Fortran code. I wanted to calculate a function called pYq_i, which is a product of mi exponential functions, see below,

The left hand side (LHS) is pYq_i, RHS is its expression. In the code, theta(1) is ki, theta(2) is Di. However ki and Di are random variables. sigma, D, are just constants, and they can be any value. Yji is the value of the data, tj is the time. E.g., t1 - t5 are 0.1,0.2,0.3,0.4,0.5.

Here is the code,

As kvantour points out, since the exponent in the numerator is squared, you can replace the term abs( D/Vi*exp(-ki*t(j)) ) with D/Vi*exp(-ki*t(j)). This allows this term to be factored out, giving a simpler exponent.

Then, replacing the product of exponentials with an exponential of a sum, and pulling as much out of the loop as possible, I get

QUESTION

What is meant by a pass in an Algorithm?

Asked 2021-Mar-04 at 04:46

I have came across a practice question from GATE PYQ's. The question asks about the pass in merge sort sorting algorithm. Below is the question:

If one uses straight two-way merge sort algorithm to sort the following elements in ascending order:

...

ANSWER

Answered 2021-Mar-04 at 04:46

The usage of the term pass implies that the question is asking about bottom up merge sort which starts by treating an array of n elements as n runs of size 1. Each pass merges even and odd runs, doubling the size of runs (except for the last run which may be shorter). The sort is done when run size >= number of elements.

Position + Euler Angles to Transformation Matrix

ANSWER

Answered 2021-Mar-02 at 02:25

In Unity, eulerAngles represent rotations in the following sequence: around Z-axis, around X-axis, around Y-axis.

We can represent this in 4x4 tranformation matrix by applying each of these rotations in matrix form:

(taken from: https://en.wikibooks.org/wiki/Cg_Programming/Unity/Rotations)

This will give you the upper-left 3x3 values of the 4x4 matrix.

PyQ and qPython are being confused here. q.sendSync('tbl') will get the variable tbl from the kdb server. This error: qpython.qtype.QException: b'tbl' means tbl doesn't exist on the kdb server. I think what you wanted is the select statement to be sent to the kdb server:
