A cubic spline is a spline constructed of piecewise third-order polynomials which pass through a set of n control points. According to [1], a cubic spline \(S(x)\) can be defined as: \(S(x)\) is a cubic polynomial \(S_j(x)\) on [\(x_j,x_{j+1}\)], for all \(j = 0,1,...,n-1\). \(S_j(x) = a...

To utilize different resources from different computer system, expecially under the condition that now we are in quarantine, remote connection is a useful and powerful tool that could help us to remotely access other computers, like the powerful computers in our lab. In this blog, I'm going to sha...
