Intel® oneAPI Math Kernel Library (oneMKL) Vector Mathematics functions
(VM) compute a mathematical function of each of the vector elements. VM
includes a set of highly optimized functions (arithmetic, power,
trigonometric, exponential, hyperbolic, special, and rounding) that
operate on vectors of real and complex numbers.
Application programs that improve performance with VM include nonlinear
programming software, computation of integrals, financial calculations,
computer graphics, and many others.
VM functions fall into the following groups according to the operations
VM Mathematical Functions
compute values of mathematical functions, such as sine, cosine,
exponential, or logarithm, on vectors stored contiguously in memory.
VM Service Functions
set/get the accuracy modes and the error codes,and create error
handlers for mathematical functions.
The VM mathematical functions take an input vector as an argument,
compute values of the respective function element-wise, and return the
results in an output vector. All the VM mathematical functions can
perform in-place operations, where the input and output arrays are at
the same memory locations. For VM mathematical functions with positive
increment indexing, in-place operations are supported only when the
input and output increments have the same value.
The oneMKL interfaces are given in:
Examples that demonstrate how to use the VM functions are located in:
