{{alias}}( x, y )
|
||
|
|
Computes the dot product of two vectors.
|
||
|
|
|
||
|
|
In general, for best performance, especially for large vectors, provide
|
||
|
|
1-dimensional ndarrays whose underlying data type is either 'float64' or
|
||
|
|
'float32'.
|
||
|
|
|
||
|
|
If provided empty vectors, the function returns `0.0`.
|
||
|
|
|
||
|
|
Parameters
|
||
|
|
----------
|
||
|
|
x: ndarray|ArrayLikeObject
|
||
|
|
First input array.
|
||
|
|
|
||
|
|
y: ndarray|ArrayLikeObject
|
||
|
|
Second input array.
|
||
|
|
|
||
|
|
Returns
|
||
|
|
-------
|
||
|
|
dot: number
|
||
|
|
The dot product.

|
||
|
|
> var y = {{alias:@stdlib/ndarray/array}}( new {{alias:@stdlib/array/float64}}( [ 2.0, 6.0, -1.0, -4.0, 8.0 ] ) );
|
||
|
|
> {{alias}}( x, y )
|
||
|
|
-5.0
|

> x = [ 4.0, 2.0, -3.0, 5.0, -1.0 ];
|
||
|
|
> y = [ 2.0, 6.0, -1.0, -4.0, 8.0 ];
