Bits array

WebA bitset stores bits (elements with only two possible values: 0 or 1, true or false, ...). The class emulates an array of bool elements, but optimized for space allocation: generally, each element occupies only one bit (which, on most systems, is eight times less than the smallest elemental type: char). Each bit position can be accessed individually: for … WebBit representation of input integers, returned as a column vector, matrix, or 3-D array. Y has the same dimensions as X except that the number of rows in Y is n times the number of rows in X.The output Y consists of n least significant bits in the specified orientation. If n is less than the number of required bits to represent the values in X, then the output Y …
