Package vecf64 provides common functions and methods for slices of float64. In the days of yore, scientists who computed with computers would use arrays to represent vectors, each value representing magnitude and/or direction. Then came the C++ Standard Templates Library, which sought to provide this data type in the standard library. Now, everyone conflates a term "vector" with dynamic arrays. In the C++ book, Bjarne Stroustrup has this to say: Go has a better name for representing dynamically allocated arrays of any type - "slice". However, "slice" is both a noun and verb and many libraries that I use already use "slice"-as-a-verb as a name, so I had to settle for the second best name: "vector". It should be noted that while the names used in this package were definitely mathematically inspired, they bear only little resemblance the actual mathematical operations performed. The names of the operations assume you're working with slices of float64s. Hence `Add` performs elementwise addition between two []float64. Operations between []float64 and float64 are also supported, however they are differently named. Here are the equivalents: You may note that for the []float64 - float64 binary operations, the scalar (float64) is always the first operand. In operations that are not commutative, an additional function is provided, suffixed with "R" (for reverse) This package does not provide range checking. If indices are out of range, the functions will panic. This package should play well with BCE. TODO: provide SIMD vectorization for Incr and []float32-float64 functions. Pull requests accepted
