Hello
As per my understanding, you want to create a distance matrix between points of type A and type B. You can do that by creating a matrix and initializing all entries to 0 and using a for loop you can find the distances and update the matrix accordingly. After generating the matrix, you can select a row where all distances would be there from a point in type A and sorting it can give the points with least distance, etc. The following code is just a small illustration for the same.
%Taking values for xA,yA,zA and xB,yB,zB
xA=[1 2 3 4 5];
yA=[1 2 3 4 5];
zA=[1 2 3 4 5];
xB=[5 4 3 2 1];
yB=[5 4 3 2 1];
zB=[5 4 3 2 1];
%Rows and columns of the matrix
M=length(xA);
N=length(xB);
distance_matrix=zeros(M,N);%Initializing the matrix
for i=1:M
for j=1:N
d=sqrt((xA(i)-xB(j)).^2+(yA(i)-yB(j)).^2+(zA(i)-zB(j)).^2);
distance_matrix(i,j)=d;%Updating the distances
end
end
For more information on how to use sortrows please refer to the following link
Hope it helps.
