DISTEUCLCART Function

Computes the distance with an Euclidean metric in cartesian coordinates.

Usage

d = DISTEUCLCART(x, y)

Input Parameters

x — An (p, n) array of p points in n-dimensional cartesian space.

y — An (q, n) array of q points in n-dimensional cartesian space.

Returned Value

d — An (p, q) array where d(i, j) is the square of the Euclidean distance between points x(i, *) and y(j, *). The result is computed with the precision of the higher input dataype, so input should generally be of type floating-point.

Keywords

None.

Discussion

The DISTEUCLCART function computes square of the Euclidean distance from each point in the first input array to each point in the second input array. All points must be specified in cartesian coordinates, but the dimension of the space is arbitrary.

Example

PM, DISTEUCLCART(REPLICATE(0.0,3,2), [[3.0,6.0], [4.0,8.0]])
; PV-WAVE prints:
;       25.0000       100.000
;       25.0000       100.000
;       25.0000       100.000
