(double-array-dot-product dbl-array1 dbl-array2)

The dot product is the sum of the products of the corresponding entries of two vectors. Geometrically, the dot product is the product of the Euclidean magnitudes of the two vectors and the cosine of the angle between them.

(double-array-map f dbl-array)

(double-array-map f dbl-array1 dbl-array2)

(double-array-map f dbl-array1 dbl-array2 dbl-array3)

Similar to [[map]] but for double arrays. First array must be the shortest.

The mean of the elements in dbl-array.

double-array-norm clj

(double-array-norm dbl-array)

The square-root of the sum of the squared values of the elements.

double-array-norm1 clj

(double-array-reduce-kv f init-dbl dbl-array1 dbl-array2 dbl-array3)

Similar to [[reduce-kv]] but for double arrays. First array must be the shortest. Calls f with the return value, index, and the value(s) at that index.

double-array-second-moment clj

(double-array-second-moment dbl-array)

The second moment of the elements in dbl-array.

double-array-set! clj

(double-array-set! dbl-array index dbl)

double-array-sort! clj

(double-array-sort! dbl-array)

Sorts dbl-array.

double-array-sorted-find clj

(double-array-sorted-find dbl-array dbl)

Searches the specified array of doubles for the specified value using the binary search algorithm, and returns the index. If the specified value does not exist, then will return negative index of where value would fit in, starting at -1 at ending at negative (count + 1). The array must be sorted (as by the double-array-sort! function prior to making this call. If it is not sorted, the results are undefined. If the array contains multiple elements with the specified value, there is no guarantee which one will be found. This method considers all NaN values to be equivalent and equal.

double-array-std-dev clj
