This class manages a set of (x_i,y_i) points, x_i must be sorted.
Those values are then used to linearly interpolate the y value for a given x. If x is less than the minimum x_0, y_0 is returned, if x is more than the maximum x_n, y_n is returned.
◆ clear()
void InterpolationArray::clear |
( |
| ) |
|
|
inline |
Removes all saved values from this object.
◆ get()
float InterpolationArray::get |
( |
float |
x | ) |
const |
|
inline |
Returns the interpolated Y value for a given x.
◆ getReverse()
float InterpolationArray::getReverse |
( |
float |
y | ) |
const |
|
inline |
Returns the X value necessary for a specified Y value.
If it's not possible to find a corresponding X (y is too small or too large), x_min or x_max is returned.
◆ getX()
float InterpolationArray::getX |
( |
unsigned int |
i | ) |
const |
|
inline |
Returns the X value for a specified point.
◆ getY()
float InterpolationArray::getY |
( |
unsigned int |
i | ) |
const |
|
inline |
Returns the Y value for a specified point.
◆ push_back()
int InterpolationArray::push_back |
( |
float |
x, |
|
|
float |
y |
|
) |
| |
|
inline |
Adds the value pair x/y to the list of all points.
It is tested that the x values are added in order.
- Parameters
-
- Returns
- 0 If the x values are not sorted, 1 otherwise.
◆ setY()
void InterpolationArray::setY |
( |
unsigned int |
i, |
|
|
float |
y |
|
) |
| |
|
inline |
Sets the Y value for a specified point.
◆ size()
unsigned int InterpolationArray::size |
( |
| ) |
const |
|
inline |
Returns the number of X/Y points.
