Question #62024

Distance between two points (x1, y1) and (x2, y2) is defined by:

distance = sqrt((x1-x2)^2+(y1-y2)^2)

Write a matlab function computeDistance that computes the distance between two points, with the

following signature.

function d = computeDistance(p1, p2)

Inputs:

p1 - coordinates of the first point as a vector with coordinates [x1 y1]

p2 - coordinates of the second point as a vector with coordinates [x2 y2]

Output:

d - the distance between the two points

distance = sqrt((x1-x2)^2+(y1-y2)^2)

Write a matlab function computeDistance that computes the distance between two points, with the

following signature.

function d = computeDistance(p1, p2)

Inputs:

p1 - coordinates of the first point as a vector with coordinates [x1 y1]

p2 - coordinates of the second point as a vector with coordinates [x2 y2]

Output:

d - the distance between the two points

Expert's answer

function d = computeDistance(p1, p2)

d = sqrt((p1(1)-p2(1))^2+(p1(2)-p2(2))^2);

Apply function:

computeDistance([1 1],[0 0])

ans =

1.4142

d = sqrt((p1(1)-p2(1))^2+(p1(2)-p2(2))^2);

Apply function:

computeDistance([1 1],[0 0])

ans =

1.4142
