Linear Algebra
Speed up linear algebra computations with low-level routines that operate on vectors and matrices, and are compatible with these industry-standard BLAS and LAPACK operations:

• Level 1: Vector-vector operations
• Level 2: Matrix-vector operations
• Level 3: Matrix-matrix operations

Sparse Linear Algebra Functions

Perform various operations on sparse matrices with low-level and inspector-executor routines including the following:

• Multiply sparse matrix with dense vector
• Multiply sparse matrix with dense matrix
• Solve linear systems with triangular sparse matrices
• Solve linear systems with general sparse matrices

Fast Fourier Transforms (FFT)

Transform a signal from its original domain (typically time or space) into a representation in the frequency domain and back. Use FFT functions in one, two, or three dimensions with support for mixed radices. The supported functions include complex-to-complex and real-to-complex transforms of arbitrary length in single-precision and double-precision.

Random Number Generator Functions (RNG)
Use common pseudorandom, quasi-random, and non-deterministic random number engines to solve continuous and discrete distributions.

Data Fitting

Provide spline-based interpolation capabilities that you can use to approximate functions, function derivatives or integrals, and perform cell search operations.

Vector Math
Balance accuracy and performance with vector-based elementary functions. Manipulate values with traditional algebraic and trigonometric functions.

Summary Statistics 
Compute basic statistical estimates (such as raw or central sums and moments) for single- and double-precision multidimensional datasets.
