[Solved] Basic example of how to do numerical integration in C++

by

Numerical derivation and integration in code for physics, mapping, robotics, gaming, dead-reckoning, and controls Pay attention to where I use the words “estimate” vs “measurement” below. The difference is important. Measurements are direct readings from a sensor. Ex: a GPS measures position (meters) directly, and a speedometer measures speed (m/s) directly. Estimates are calculated projections … Read more

[Solved] how to calculate integral with R

by

In mathematics, an integral is the area under the curve. In your example, you want the area under the curve as defined by position and rate. position <- c(2,34,58) rate <- c(14, 20, 5) plot(position, rate, type=”l”, ylim=c(0, 25)) You can calculate the area under the curve by hand, using the trapezoidal rule: 32*17 + … Read more
