#### Function template `scaled` <a id="linalg.scaled.scaled">[[linalg.scaled.scaled]]</a>
|
| 2 |
+
|
| 3 |
+
The `scaled` function template takes a scaling factor `alpha` and an
|
| 4 |
+
`mdspan` `x`, and returns a new read-only `mdspan` with the same domain
|
| 5 |
+
as `x`, that represents the elementwise product of `alpha` with each
|
| 6 |
+
element of `x`.
|
| 7 |
+
|
| 8 |
+
``` cpp
|
| 9 |
+
template<class ScalingFactor,
|
| 10 |
+
class ElementType, class Extents, class Layout, class Accessor>
|
| 11 |
+
constexpr auto scaled(ScalingFactor alpha, mdspan<ElementType, Extents, Layout, Accessor> x);
|
| 12 |
+
```
|
| 13 |
+
|
| 14 |
+
Let `SA` be `scaled_accessor<ScalingFactor, Accessor>`.
|
| 15 |
+
|
| 16 |
+
*Returns:*
|
| 17 |
+
|
| 18 |
+
``` cpp
|
| 19 |
+
mdspan<typename SA::element_type, Extents, Layout, SA>(x.data_handle(), x.mapping(),
|
| 20 |
+
SA(alpha, x.accessor()))
|
| 21 |
+
```
|
| 22 |
+
|
| 23 |
+
[*Example 1*:
|
| 24 |
+
|
| 25 |
+
``` cpp
|
| 26 |
+
void test_scaled(mdspan<double, extents<int, 10>> x)
|
| 27 |
+
{
|
| 28 |
+
auto x_scaled = scaled(5.0, x);
|
| 29 |
+
for (int i = 0; i < x.extent(0); ++i) {
|
| 30 |
+
assert(x_scaled[i] == 5.0 * x[i]);
|
| 31 |
+
}
|
| 32 |
+
}
