26.7 Numeric arrays [numarray]

26.7.2 Class template valarray [template.valarray]

26.7.2.3 Assignment [valarray.assign]

🔗
valarray& operator=(const valarray& v);
1
#
Effects: Each element of the *this array is assigned the value of the corresponding element of v.
If the length of v is not equal to the length of *this, resizes *this to make the two arrays the same length, as if by calling resize(v.size()), before performing the assignment.
2
#
Postconditions: size() == v.size().
3
#
Returns: *this.
🔗
valarray& operator=(valarray&& v) noexcept;
4
#
Effects: *this obtains the value of v.
The value of v after the assignment is not specified.
5
#
Returns: *this.
6
#
Complexity: Linear.
🔗
valarray& operator=(initializer_list<T> il);
7
#
Effects: Equivalent to: return *this = valarray(il);
🔗
valarray& operator=(const T& v);
8
#
Effects: Assigns v to each element of *this.
9
#
Returns: *this.
🔗
valarray& operator=(const slice_array<T>&); valarray& operator=(const gslice_array<T>&); valarray& operator=(const mask_array<T>&); valarray& operator=(const indirect_array<T>&);
10
#
Preconditions: The length of the array to which the argument refers equals size().
The value of an element in the left-hand side of a valarray assignment operator does not depend on the value of another element in that left-hand side.
11
#
These operators allow the results of a generalized subscripting operation to be assigned directly to a valarray.
