| When $x \sim \mathcal{N}(\mu, \sigma^2)$: $$E\left[\sin(x)\right] = \sin(\mu)\;e^{-\frac{\sigma^2}{2}}$$ Reference: [Compute E(sinX) if X is normally... |
| So, is this a useless result? |
| This is how Mathematica appears on the 4k display of my machine with Ubuntu 18.04. ![enter image description here][1] For comparison I leave the Options window open. I certainly can set Notebook Maginification to 200% in order to be able to... |
| How is the Dot product implemented in Mathematica? Let's take for instance matrix multiplication. I have a C++ function which does that in a more or less traditional way, but also making appropriate use of the cache memory, with parallelism and... |
| I have a data-set on which I want to run the `Classify[]` function. To extract features I will make use of the `FeatureExtraction[]` function. My question is: should I extract the features before I split the data into the training set and... |
| But, it should give me at least the same solutions as the ones obtained when solving over Reals, no? |
| Thank you, Sander. Exp outside and Random Number generation with specified mean and standard deviation is a nice tip. I don't know very well how to write Mathematica code to be compiled in C. Nevertheless, I tried that below, but it does not... |
| I have a poor machine, Gianluca.. and a bit weird I guess, because it gives me that the implementation with "=" is slower than the one with ":=" |
| Seemingly an easy task: How to adapt the code above to produce a matrix of real numbers? Here are the changes I have done so far: #include "WolframLibrary.h" extern "C" __declspec(dllexport) int... |
| [Overleaf][1] is a nice website which allows collaborative writing and publishing of LATEX documents. I am currently working on a document. I need to make some modifications to the file there. To give a simplified example, in the hyperlinked... |
