Euclidean distance between two points.
显示 更早的评论
I need to create a function that calculates the euclidean distance between two points A(x1,y1) and B(x2,y2) as d = sqrt((x2-x1)^2+(y2-y1)^2)).
Am lost please help.

Sir im a researcher.Im working on emotion recognition classification through eyes and eyebrows.I have detected/cropped the feature ,now i need to calculate the distance between the nodal points in eye through matlab.I will calculate the distance of eyes for different expressions.Based om that i will determine the expression.Can u help me out.???

You can use D = pdist(X) to calculate pairwise isdtance in MATLAB, default distance is Euclidean. If you want to compare with other distance metrices like cityblock etc. then use D = pdist(X,distance)

Do you know how to create functions yet? You just do this:
function [output1 output2] = yourFunction(input1, input2, input3) % Then your code (like you gave above).
Change the inputs and outputs to what you need (like my "input1" = your "x1" etc.), save it in an m-file and then you're done. Let me know if you still need my hint to be more explicit, and if this is a homework question.

function euclideanDistance = CalcDistance(x1, y1, x2, y2)
euclideanDistance = sqrt((x2-x1)^2+(y2-y1)^2);
