HELLO; who can help me to correct this code? I want to superimpose or compare the points insitu on the image:

ncdist=zeros(4320,8640); dist=dist+10000; % matrice des distances    
lon = ncread('D:\K\A20130572013064.L3m_8D_CHL_chlor_a_4km.nc','lon') ;
lat = ncread('D:\K\A20130572013064.L3m_8D_CHL_chlor_a_4km.nc','lat') ;
chlor_a= ncread('D:\K\A20130572013064.L3m_8D_CHL_chlor_a_4km.nc','chlor_a') ;

% plot here     

chlor_a=double(chlor_a);   
data1=chlor_a*0.000717185-2;   
none=data1<45;    
data1=data1.*none; 
DiffTemp=[];

% matrice qui va contenir le résultat du code

num=xlsread('C:\Users\User\Desktop\Chla\SECTEUR OUEST.xlsx');for k=1:size(num)   
for d=3505:3645     
for s=0170:0065            
dist(d,s) = sqrt( (num(4)-lat(d))^2 + (num(5)-lon(s))^2 );    
end   
end    

[minval,ind] = min(dist(:));

% on retient les indices qui correspondent à la distance minimale    

[I,J] = ind2sub([size(dist,1) size(dist,2)],ind);
% on converti les indices en I,J    
DiffTemp= [num(4),num(5),num(3),data1(I,J)];
end
