class (BLAS1 e, Tensor x i e) => ITensor x i e where Source

A class for immutable tensors. Methods size :: x e -> Int Source Get the numer of elements stored in the tensor. (//) :: x e -> [(i, e)] -> x e Source Get a new tensor by replacing the elements at the given indices. unsafeAt :: x e -> i -> e Source Get the value at the given index, without doing any bounds-checking. unsafeReplace :: x e -> [(i, e)] -> x e Source Same as '()' but doesn't do any bounds-checking. indices :: x e -> [i] Source Get the indices of the elements stored in the tensor. elems :: x e -> [e] Source Get the elements stored in the tensor. assocs :: x e -> [(i, e)] Source Get the list of (index, element) pairs stored in the tensor. amap :: ITensor x i e' => (e -> e') -> x e -> x e' Source Apply a function elementwise to a tensor. azipWith :: (ITensor x i f, ITensor x i g) => (e -> f -> g) -> x e -> x f -> x g Source Apply a function to pairs of elements of tensors that are the same shape.

(!) :: (ITensor x i e, Show i) => x e -> i -> e Source

Get the value at the given index. Range-checks the argument.
