| Does anyone know of any (worthwhile) examples of iOS apps created for Wolfram Player? I've played around with it a little, enough to discover that, with the exception of textbook apps, most CDF-apps are virtually unusable, at least on my iPhone. ... |
| It's rather fun to experiment with Mathematica's ImageRestyle function, which can produce some interesting results when applied iteratively. In this illustration we start with a photographic image of Zurich: img = ![enter image description... |
| I am using Mathematica V12.3 on an Aurora-Ryzen with GeForce RTX 2090 and v11.3 of the NVIDIA toolkit. All the latest paclets/drivers are installed. There are multiple reports of Mathematica not working properly with NVIDIA CUDA (cf... |
| I have written extensively about statistical arbitrage strategies in other posts, for example: - [Succesful Statistical Arbitrage][1] - [Developing Statistical Arbitrage Strategies Using Cointegration][2] - [Pairs Trading with Copulas][3] ... |
| Over on Stack Exchange a [user][1] posted the following [question][2]: > This is a basic question about using the KalmanFilter function. I > want to use the KalmanFilter function (or other related Kalman Filter > functions in Mathematica) to... |
| Is it just me, or are community posts not being updated? I recently received email notification that some posts I follow had been updated, but I don't see the updates. For example, I don't see this post (or various others I have been notified of,... |
| This is a snippet from a strategy backtesting system that I am currently building in Mathematica. One of the challenges when building systems in WL is to avoid looping wherever possible. This can usually be accomplished with some thought, and the... |
| *MODERATOR NOTE: This post contains parts written by [kglr][1], which can be found [here][2].* ---------- I am sharing this because it's a commonly occurring issue in financial time series, and other applications. I have a time series... |
| I realize that I am possibly the only Mathematica user to suffer from existential angst for the product, but still, its worth pausing to ask the question, what is Mathematica for? Meaning, what is its purpose? But for those of you pragmatists... |
