Equations

A number of rules of thumb exist for the advantages of non-coherent averaging, I wanted to see, in a fairly practical way, what the advantage really was. This turned out to be more complex than I thought, because you have to identify and implement separate parts to the equations for the output...

the function is GUI that simulate double pendulum by using 4th-order Runge-Kutta algorithm for the differential equations.the differential equation are very similar to eq. (12) and (13) here:http://home1.fvcc.edu/~dhicketh/DiffEqns/spring09projects/LauraStickel/Double%20Pendulum.pdf

This block implements the PID control equations found on page 1680 of the Foxboro I/A Series Integrated Control Block Descriptions Manual Volume 3, dated May 31 2006. Use this block when the target platform for a PID control design is a Foxboro I/A Series DCS.These blocks have been field verified...

The conjugate gradient method aims to solve a system of linear equations, Ax=b, where A is symmetric, without calculation of the inverse of A. It only requires a very small amount of membory, hence is particularly suitable for large scale systems.It is faster than other approach such as Gaussian...
