# What is wolfram mathematica: Definition and 16 Discussions

Wolfram Mathematica is a software system with built-in libraries for several areas of technical computing that allow machine learning, statistics, symbolic computation, data manipulation, network analysis, time series analysis, NLP, optimization, plotting functions and various types of data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other programming languages. It was conceived by Stephen Wolfram, and is developed by Wolfram Research of Champaign, Illinois. The Wolfram Language is the programming language used in Mathematica. Mathematica 1.0 was released on June 23, 1988 in Champaign, Illinois and Santa Clara, California.

1. ### Mathematica Neural networks in Wolfram Mathematica

Hello, I have a question about the use of functions and overall creation of neural networks in the Wolfram Mathematica (WM) program. I wonder if it is realistic to make meaningful neural networks usable at least partially for scientific research in WM? By scientific research, I do not mean the...
2. ### Mathematica Loop integrals using Package-X 2.0 in Wolfram Mathematica

Hello everyone, I have trouble installing Package-X 2.0 to Wolfram Mathematica. It says that the package should be available at https://packagex.hepforge.org but this page does not open. I tried everything I could to install and load this package but it was all unsuccessful. It seems as the...
3. ### Path Integrals in Wolfram Mathematica

Hello everyone ! I am new to this site so I 'd better say hello to you all ! I am finishing my BR in physics and part of this ending is to deliver a thesis . Long story short I must compute path-integrals in SU(2) and SU(3) pure yang-mills fields . Problem is that i was never very good with...
4. ### Can Wolfram Mathematica be wrong on this Integration?

Homework Statement Mathematica vs (Symbolab + my brain) Homework EquationsThe Attempt at a Solution I think this integral calculation in Mathematica is wrong. Open pictures below. Please help me. Graphs (the red one is under the blue and the green): https://ibb.co/bACa3G Wolfram Mathematica...
5. ### Wolfram Mathematica demonstrations programming book

I am currently a complete beginner to Mathematica (in fact, to programming in general) I have done adequate research about books for general books on Mathematica, but I would like to find a book that focuses mostly on graphics, animations, demonstrating physics and the like. For example, while...
6. ### Wolfram Mathematica: ListPlot3D to SphericalPlot3D

Hello! There is a problem with Mathematica: i calculate an integral with a help of NIntegrate and get the whole list of spherical coordinates, like {6.24, 3.14, 0.323488}, {6.26, 3.14, 0.323488}, {6.28, 3.14, 0.323488} and so on... then i create a list, like data = List[{6.24, 3.14, 0.323488}...
7. ### Mathematica Division of sequences in Wolfram Mathematica

How to divide two sequences in Wolfam Mathematica? For example f_n=\frac{1}{n}=1,\frac{1}{2},\frac{1}{3},... and g_n=n^2=1,4,9,... I want to get h_n=1,\frac{1}{8},\frac{1}{27}...=\frac{f_n}{g_n} How to do that in Wolfram Mathematica?
8. ### Mathematica How to get smaller-size eps figures from Wolfram mathematica?

Dear every Mathematino-s in high energy physics I knew several workers in computer and mathematics, but few of them know wolfram mathematica software, so I think it is justified to let my question appear here. I use wolfram-mathematica to make 3D figures and want to use them...
9. ### [Wolfram Mathematica] - how scripts work in Mathematica

[Wolfram Mathematica] -- how scripts work in Mathematica Hi. This is not a homework. I just did a script in Octave and I've just finished writing it on Wolfram Mathematica. The problem is that I don't know how to define the function, I don't know how scripts work in Mathematica. My script...
10. ### [Wolfram Mathematica] Using Newton's method to solve non-linear system

Hi. This is not actually not part of the homework; but it's something I'd like to do. I have to solve the following system using Newton-Raphson's method: $$\begin{matrix} \frac{X}{\mu }+Y=1 \\ X=\left( \lambda -\left( K-1 \right)X \right)Y \\ \end{matrix}$$ Surfing the...

Does anybody know how to plot the Riemann surface of complex functions on wolfram Mathematica 8.0 ?
12. ### Analytical Bra-Ket Tensor Products: Rules & Wolfram Mathematica

What are the rules of analytical – not numerical (matrix) entry of bra-ket convertion – operations on bra-ket, in particular – tensor product ? For example – how in analytical form to do this: U|\Psi\rangle where: U=I\otimesI I=|0\rangle\langle0|+|1\rangle\langle1|...
13. ### How to plot a function with several constants using Wolfram Mathematica

How can I plot this probability density function using Wolfram Mathematica Keeping the constants the same. ψ*ψ= A^2 (x^2)exp(-2a(mx^2/h)) ; where m,a,A,and h are constants and I want the graph in terms of them. I tried: Plot[A^2 *(x^2)*exp(-2a(mx^2/h)),{x,-1000,1000}]

16. ### Mathematica Can someone please explain how to write functions in Wolfram Mathematica ?

I'm good in writing functions in Matlab , however since moving to Mathematica , I find it pretty hard to write them . For instance I need to write a function that returns a [1,0,-1] to integers, meaning x>0 , x==0 , x<0 with a single If , but I didn't find a way with one (only two)...
