Analyze data and develop algorithms in a desktop environment designed for the way you work.

MATLAB Speaks Math

The matrix-based MATLAB language is the world’s most natural way to express computational mathematics. Linear algebra in MATLAB looks like linear algebra in a textbook. This makes it straightforward to capture the mathematics behind your ideas, which means your code is easier to write, easier to read and understand, and easier to maintain.
You can trust the results of your computations. MATLAB, which has?strong roots in the numerical analysis research community, is known for its impeccable numerics. A MathWorks team of 350 engineers continuously verifies quality by running millions of tests on the MATLAB code base every day.
MATLAB does the hard work to ensure your code runs quickly. Math operations are distributed across?multiple cores?on your computer, 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 or by changing standard arrays into GPU or distributed arrays. Run?parallel algorithms?in infinitely scalable public or private clouds with no code changes.
The MATLAB language also provides features of traditional programming languages, including flow control, error handling, object-oriented programming, unit testing, and source control integration.
