#### Type Parameters

T

The type of the elements in the vector. `T` can be any primitive numeric type.

## Remarks

Vector<T> is an immutable structure that represents a single vector of a specified numeric type. The count of Vector<T> instances is fixed, but its upper limit is CPU-register dependent. It's intended to be used as a building block for vectorizing large algorithms, and therefore cannot be used directly as an arbitrary length vector or tensor.

The Vector<T> structure provides support for hardware acceleration.

The term primitive numeric data type in this article refers to numeric data types that are directly supported by the CPU and have instructions that can manipulate those data types.

Reinterprets the bits of the specified vector into a vector of type UInt32. Reinterprets the bits of the specified vector into a vector of type UInt64. Reinterprets the bits of a source vector into a vector of native-sized, unsigned integers. Returns a value that indicates whether any single pair of elements in the specified vectors is equal. Shifts each element of a vector left by the specified amount. Multiplies a vector by a specified scalar value. Multiplies a vector by a specified scalar value. Returns a new vector whose values are the product of each pair of elements in two specified vectors.
