Is there an option to tell Mathematica not to use iconized in its output? I find these so annoying. The design is all wrong to tell you the truth. The default should be the other way around. It should …

The Eliminating Variables section on Manipulating Equations and Inequalities documentation quotes an otherwise undocumented feature for Solve …

I have a list of ~50 numbers (they’re all whole, but I don’t know if it matters) and I’d like to split it into lists of exactly five entries so that the sum of each group of five is the most similar …

I am having an issue where if I provide the EllipticE function with a first argument of zero and a second argument with a precision lower than that of machine precision, the kernel crashes. For …

This question was inspired by the game Planarity in which a player tries to position the vertices so that no two lines cross. As I move the vertices, the change in the number of crossings is detected …

I want to generate a list of adjacency matrices of size $n=4$ s.t. The diagonal is zero: $a_{ii}=0$ for all $i\in\lbrace 1,2,…,n\rbrace$ There are no 2-cyles, i.e. if $a_{ij}==1$, then $a_{ji}==0$ …

I am trying to use the Export command to convert a list of plots into a *.gif file, and the command runs and executes well, but I can’t find the file! Where is it …

I am wondering how to implement the multi-peak detecting and fitting in Mathematica. Following is an example of fitting the data using three peaks (such that the data ~ peak1 + peak2 + peak3). The …

I recently came across this video: Mathematically correct breakfast, which shows how a bagel can be neatly sliced into two identical linked halves. I’d like to try this with Mathematica. Here’s a …

Deep convolutional neural networks are very good at computer vision related tasks. Optical Character Recognition (OCR) is one important branch of computer vision. In fact, the convolution neural …

When I solve the aforementioned equation for $W$ or $A$ on Mathematica I get a long and ugly equation in return, namely one of the solutions for $W$ is: (attempt to read at your own health) …

As you may already know, Mathematica is a wonderful piece of software. However, it has a few characteristics that tend to confuse new (and sometimes not-so-new) users. That can be clearly seen from …

How would I plot $x^2+y^2=1$ in 3D (it would form a cylinder)? Since there is no $z$ in the equation, I can’t solve for it and use Plot3D. Or can I just put the …

Can you answer these questions?

I have a sum like f = Sum[x[i]^2, {i,1,Infinity}] and I want to take a derivative of this with respect to one of the variables, e.g. …

Assume I am given a list of all the pairwise dot products of an unknown set of $n$ vectors. How can I efficiently generate such a set (or all possible sets) with the extra constraint that all vectors …
