MATLAB：pdist函数中的多个出现数据：如何？

Question

MATLAB：我们有数据给出出现的x y坐标。通常在一个位置上有多于1个出现。当我们想在函数pdist中使用这些数据时，这会产生问题。我们试图将数据更改为具有x y坐标的列表，用于EACH出现，但到目前为止尚未管理。有人有解决方案吗？

% initial values m = 0;
[X,Y,People,Positive] = textread('Loaloa_data.txt', '%f%f%f%f', 'headerlines', 1); 
LoaData = [X,Y,People, Positive]; 

%calculate percentage of infected people per location 
Percentage_per_Location = (Positive(:)./People(:))*100; 

%calculate percentage of total infected people per location 
TotPos = sum(Positive); 
Percentage_of_Total = Positive(:)./TotPos*100; 
LoaData = [X,Y,People,Positive,Percentage_per_Location, Percentage_of_Total];

%Make a new frequency table in which every value of Positive has a x and y 
%value. 
% first make a new matrix with x and y coordinated and positive values. 
LengthColumn = (1:197)'; 
Matrix1 = [LengthColumn,X,Y,Positive]; 
Freq = zeros(sum(Positive(:)),2) ; 

% r = Matrix1(:,1) 
% CumFreq = ([1: sum(Positives)]); 
% Freq = Matrix1(:,4); 
% xyData =zeros(length(Freq),2); 
for i=1:length(Matrix1(:,1)) 
    %for m<=TotPos 
    F = Matrix1(i,4) 
    for j =[1:F] 
        m = m+j 
        Freq(m,1:2) = Matrix1(i,2:3) 
    end 
    % end 
end
