such as those coming from hyperthreading technology. The “4” here indicates that four physical CPU cores are detected. To override this setting, either use theLaunchKernels[n]function, wherenis an integer indicating the number of local subkernels to launch, or switch to the manual setting. ...
Both functions effectively start by replacing the smallest pieces of your expression by finite‐order, or finite‐precision, approximations, and then evaluating the resulting expression. If there are, for example, cancellations, this procedure may give a final result whose order or precision is less...

I initially added rules in order of definition to get assignment working, but then went back and added a simple specificity ordering function (The exact details for how Mathematica handles pattern specificity are not so easy to find. I didn’t try too hard to reverse engineer it; I just ...
After evaluating the function definition above, just runupdateMaTeX[], then<<MaTeX`to load the updated version. Usage UseMaTeX[texcode]orMaTeX[expression]to typeset using LaTeX. The latter will automatically applyTeXFormtoexpression. The LaTeX code is interpreted in math mode. Remember to escap...

Notice that you cannot run more Wolfram kernels than your license allows (see the function(wolframite.core/kernel-info!)) Wolframite is open-source and targeted at applications in scientific computing, computational economics, finance, and other fields that rely on the combination of parallelized simu...

One major flaw in the Cardano3 design was an attempt to create a container and user interface that would handle all complex-function graphics. It is now recognized that packages should not create new interfaces, which are just additional specialized things that students have to learn, but shoul...
By the way, when we “support a special function” these days, there’s a lot we do. It’s not just a question of evaluating the function to arbitrary precision anywhere in the complex plane (though that’s often hard enough). We also need to be able to compute ...
