# [−][src]Function arrayfire::selectr

`pub fn selectr<T>(a: &Array<T>, cond: &Array<bool>, b: f64) -> Array<T> where`

T: HasAfEnum,

Element wise conditional operator for Arrays

This function does the C-equivalent of the following statement, except that the operation happens on a GPU for all elements simultaneously.

```
c = cond ? a : b; /// where a is Array and b is a scalar(f64)
```

# Parameters

`a`

is the Array whose element will be assigned to output if corresponding element in`cond`

Array is`True`

`cond`

is the Array with conditional values`b`

is the scalar that is assigned to output if corresponding element in`cond`

Array is`False`

# Return Values

An Array
