Perfect sinc interpolation in Matlab and Python
% From http://phaseportrait.blogspot.com/2008/06/sinc-interpolation-in-matlab.html
% Ideally "resamples" x vector from s to u by sinc interpolation
function y = sinc_interp(x,s,u)
% Interpolates x sampled sampled at "s" instants
% Output y is sampled at "u" instants ("u" for "upsampled")
% (EXPECTS x, s, and u to be ROW VECTORS!!)
% Find the period of the undersampled signal
T = s(2)-s(1);

Add native libraries to Apache Hadoop installation

Apache Hadoop - add native libraries

If native libraries are not available the following message is displayed with every hadoop command: hadoop checknative

Simple automated GIT Deployment using Hooks

Simple automated GIT Deployment using GIT Hooks

Here are the simple steps needed to create a deployment from your local GIT repository to a server based on this in-depth tutorial.

How it works

You are developing in a working-copy on your local machine, lets say on the master branch. Most of the time, people would push code to a remote server like github.com or gitlab.com and pull or export it to a production server. Or you use a service like deepl.io to act upon a Web-Hook that's triggered that service.

Create a private fork of a public repository

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

  1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare git@github.com:usi-systems/easytrace.git
