MATLAB

"With MATLAB, I can code and debug a new capability much faster than with other languages. Cutting our development time in half with MATLAB was instrumental in our ability to meet a tight timeline. Our customer was convinced that I’d worked 70 hours each week when he saw the results."

Bancroft Henderson, EMSolutions

The matrix-based MATLAB language lets you express math directly.

Engineers and scientists need a programming language that expresses matrix and array mathematics directly instead of through generalized programming constructs.

Matrix math in Python requires function calls, not natural operators, and you must keep track of the differences between scalars, 1-D arrays, and 2-D arrays. Even in the simplest Python code this can be difficult, as the hidden mistake in the following example shows. The same example written in the MATLAB language shows that MATLAB is the more natural way to express computational mathematics.

Ultimately, linear algebra in MATLAB looks like linear algebra in a textbook. The same is true for data analytics, signal and image processing, control design, and other applications.

This is why more than 1,800 textbooks teach using MATLAB.

Engineers and scientists deserve tools that fit the way they work. They shouldn’t have to adapt the way they work to fit their tools.

Python functions are typically designed and documented by advanced programmers for other experienced programmers. Python development environments for scientific computing lack the reliability and integration of the MATLAB desktop.

Everything about MATLAB is designed specifically for engineers and scientists:

  • Function names and signatures are familiar and memorable, making them as easy to write as they are to read.
  • New function interfaces undergo a rigorous design process that typically involves dozens to hundreds of developer-hours per function.
  • The desktop environment is tuned for iterative engineering and scientific workflows.
  • Integrated tools support simultaneous exploration of data and programs, letting you explore more ideas in less time.
  • Documentation is written for engineers and scientists, not computer scientists.

“As a process engineer I had no experience with neural networks or machine learning. I worked through the MATLAB examples to find the best machine learning functions for our predictive metrology use case. I couldn’t have done this in C or Python—it would’ve taken too long to find, validate, and integrate the right packages.”

Emil Schmitt-Weaver, ASML

Proven MATLAB toolboxes provide the functions and capabilities you need. Period.

A programming language must be combined with specialized tools that support what you need to do, whether you’re modeling economic data, analyzing an image sequence, or driving a robot. Those tools need to work, and they need to work together.

Python relies on community-authored packages for scientific and engineering functionality. Python packages vary widely in quality and capabilities. Each package has its own stand-alone documentation, putting the burden on you to piece together a solution.

Unlike Python, MATLAB toolboxes offer professionally developed, rigorously tested, field-hardened, and fully documented functionality for scientific and engineering applications. Toolboxes are designed to work with each other, and they integrate with parallel computing environments, GPUs, and automatic C code generation. They are updated together, so you never struggle with incompatible library versions.

We need to filter our data, look at poles and zeroes, run nonlinear optimizations, and perform numerous other tasks. In MATLAB, those capabilities are all integrated, robust, and commercially validated.

MATLAB apps let you complete tasks more easily than with custom programming.

Python doesn’t offer integrated workflow apps for scientific and engineering applications, requiring custom programming instead. This slows down discovery and exploration, especially for highly iterative workflows.

MATLAB apps let you start working right away. These interactive applications combine direct access to large collections of algorithms with immediate visual feedback. You can try a new surface fitting algorithmfilter design technique, or machine learning classification algorithm and see right away how it works with your data. Iterate until you’ve got the results you want, then automatically generate a MATLAB program to reproduce or automate your work.

MATLAB helps automate the entire path – from research to production.

Major engineering and scientific challenges require broad coordination across teams to take ideas to implementation. Every handoff along the way risks adding errors and delays.

Unlike Python, MATLAB can help teams through their entire workflow:

MATLAB runs your programs faster – meaning you can try more ideas and solve bigger problems.

Out of the box, MATLAB is faster than Python for common technical computing tasks in statistics, engineering calculations, and data visualization. The following table and chart illustrate benchmark results.

Python code requires overlapping and conflicting add-ons to get performance benefits such as just-in-time compilation and explicit parallel programming. These solutions tend to be incomplete or targeted at advanced programmers.

MATLAB does the hard work of making your code fast. Math operations are distributed across your computer’s cores, library calls are heavily optimized, and all code is just-in-time compiled. You can run your algorithms in parallel by changing for-loops into parallel for-loops, which entails simply adding the three characters “par” to “for”, or by changing standard arrays into GPU arrays. You can run your parallel algorithms in an infinitely scalable public or private cloud with no code changes.

You can trust the results you get in MATLAB.

Engineers and scientists trust MATLAB to send a spacecraft to Plutomatch transplant patients with organ donors, or just compile a report for management. This trust is built on impeccable numerics stemming from the strong roots of MATLAB in the numerical analysis research community.

A team of MathWorks engineers continuously verifies quality by running millions of tests on the MATLAB code base every day.


Explore why scientists and engineers choose MATLAB over Python:

Capability

MATLAB

Python

Mathematical syntax

Natural syntax makes programs easier to write and read, improving communication and reducing mistakes.

  • Math- and matrix-oriented language
  • General-purpose language
  • Numeric arrays and data types not part of the core language

Ease of learning for scientific computing

Programming is a means to an end for most engineers and scientists. An easily learned program keeps the focus on the domain, not the programming.

  • Beginners write math as they would on paper.
  • Non-programmers learn as their needs grow.
  • Beginners start by learning advanced programming constructs.
  • Users must become programmers before they can be productive.
