## Do mathematicians use Mathematica?

It is beneficial , instructive and helpful for amateur mathematicians as well as for scientific researchers. In my opinion, Mathematica is one of the foremost , most poweful and most useful computer algebra systems .

## What is the difference between and == in Mathematica?

FYI, they are different functions internally. == is Equal , whereas === is SameQ . Equal refers to semantic equality whereas SameQ is syntactic equality. For instance, Sin[x]^2+Cos[x]^2 and 1 are the same number, so they are equal semantically.

## What happens if Dsolve does not return any numerical solution?

9. What happens if dsolve does not return any numerical solution? Explanation: We have to solve the differentiation numerically. To do it in MATLAB, we need to use ode45 after converting the differential equation to a system of first order differential equation.

## Can I use Mathematica online?

Mathematica Online brings the world’s ultimate computation system to the modern cloud environment. Use the power of Mathematica interactive notebooks to work directly in your web browserâ€”with no installation or configuration requiredâ€”and seamlessly share documents and resources in the cloud.

## What is ode23 Matlab?

ode23 is an implementation of an explicit Runge-Kutta (2,3) pair of Bogacki and Shampine. It may be more efficient than ode45 at crude tolerances and in the presence of moderate stiffness. ode23 is a single-step solver [1], [2].

## How can I get Mathematica for free?

## Is Mathematica fast?

Most Mathematica built-in functions which process lists create a copy of an original list and operate on that copy. This is very fast, and not just for packed numerical arrays ( Part modifies the original list). 5.3.

## Can Mathematica show steps?

Mathematica by itself does not give step by step solutions to inputs , however one can add some Mathematica symbols and assumptions , options or conditions to get additional steps or modifications related to the solutions .

## What is a Mathematica notebook?

Doing Computations in Notebooks Mathematica notebooks are structured interactive documents that are organized into a sequence of cells. Each cell may contain text, graphics, sounds or Mathematica expressions in any combination.

## What does N mean in Mathematica?

all nonzero numbers

## Is Mathematica open source?

Mathics is a free, open-source general-purpose computer algebra system featuring Mathematica-compatible syntax and functions.

## Is Mathematica a coding language?

Mathematica is often the first major software product running on new computer architectures. Mathematica is taught as a first programming language in many university courses.

## What is the advantage of Matlab over other computing software with Matrix dimensions?

6. What is the advantage of MATLAB over other computing software with matrix dimensions? Explanation: In many softwares, while declaring a matrix- the user has to assign a size of the matrix before entering any values to it.

## How do I stop Mathematica from running?

To stop this computation, first select its cell bracket: Then select Abort Evaluation from the Evaluation menu: The Wolfram System then outputs $Aborted: If Abort Evaluation does not succeed in stopping the computation, you can do so by quitting the active kernel.

## How do you solve a system of equations with an ode in Matlab?

Define these matrices and the matrix equation.

- syms x(t) y(t) A = [1 2; -1 1]; B = [1; t]; Y = [x; y]; odes = diff(Y) == A*Y + B.
- odes(t) = diff(x(t), t) == x(t) + 2*y(t) + 1 diff(y(t), t) == t – x(t) + y(t)
- [xSol(t), ySol(t)] = dsolve(odes); xSol(t) = simplify(xSol(t)) ySol(t) = simplify(ySol(t))

## Who uses Wolfram Mathematica?

Wolfram is widely used in academia, especially in physics and financial analytics. Although I guess the share is dropping also there as Python gets more and more popular. My first experience with Mathematica was during an undergraduate Maths class where I was immediately impressed by the interactive 3D plots.

## How solve diff eq in Matlab?

First, represent y by using syms to create the symbolic function y(t) .

- syms y(t)
- ode = diff(y,t) == t*y.
- ode(t) = diff(y(t), t) == t*y(t)
- ySol(t) = dsolve(ode)
- ySol(t) = C1*exp(t^2/2)

## What does := do in Mathematica?

immediate assignment: Use = if you want Mathematica to evaluate the right-hand side of the assignment when you type it in. delayed assignment: Use := if you do not want Mathematica to evaluate the right-hand side until you use it.

## Which is better Mathematica or Maple?

Mathematica and Maple have a fundamentally different approach and history, which is underscored by Mathematica’s unique design principles. In its core algorithms and in most technical application areas, Mathematica offers a deeper, more complete and better integrated collection of features.
