Calculating distance between a point and all points of a matrix

In the file.mat that I upload there are the x and y coordinates of an antenna and the 2 arrays with x and y coordinates of the entire matrix. I need to compute the distance between the antenna and the other points of the matrix. In particular I need a matrix 1440000x3 with the X_Coord in the 1st column, Y_Coord in the 2nd column and the distances in the 3rd.

pdist2()

Answer 1

If you have Statistics and Machine Learning Toolbox, you can simply use pdist2 to do that.

Otherwise, you can also do that using basic MATLAB function, like:

d = sqrt((X_Coord - X_Ant).^2 + (Y_Coord - Y_Ant).^2);
