FFT Performance Benchmarks in .NET

Posted on January 5, 2011March 1, 2016 by Paul Shirkey

We've had a number of inquires about the CenterSpace FFT benchmarks, so I thought I would code up a few tests and run them on my machine. I've included our FFT performance numbers and the code that generated those numbers so you can try them on your machine. (If you don't have NMath, you'll need to download the eval version). I also did a comparison of 1 dimensional real DFTs, with FFTW, one of...

Finding Peaks in Data with NMath

Posted on October 13, 2010March 1, 2016 by Paul Shirkey

Finding peaks in experimental data is a very common computing activity, and because of its intuitive nature there are many established techniques and literally dozens of heuristics built on top of those. CenterSpace Software has jumped into this algorithmic fray with a new peak finding class based on smooth Savitzy-Golay polynomials. If you are not familiar with Savitzy-Golay polynomial smoothi...

Statistical Quality Control Charts

Posted on August 11, 2010March 1, 2016 by Paul Shirkey

Statistical quality control charts, or Shewart quality control charts, are used across nearly all sectors of industry to maintain and improve product quality. Quality control charts provide a means to detect when a time varying process exceeds its historic process variation and needs analysis and/or intervention to remedy the out-of-control process (known as special cause variation). These proce...

Searching for Roots in Univariate Functions

Posted on July 21, 2010July 21, 2010 by Paul Shirkey

Finding the roots of a univariate function is a basic numerical procedure that nearly all engineers and scientists encounters at some point, because the root finding question addresses the basic equation, where, x can be a real or complex variable. Or more generally, we can solve, by finding the roots to, Algorithms I will demonstrate three well known univariate root findin...
