I have a code here that finds the data i need for specific cell values, for some reason it breaks when i get to the 27th iteration. Which to me doesn't make sense as everything should be within the desired range and the matrix dimensions agree, any help would be appreciated
PM = ('C:\Users\jorda\Desktop\Physics Project\PM Dust Not Removed\ACAG_PM25_V4GL03_199801_199812_0p05.nc');
x_val = ncread(PM,'LAT');
y_val = ncread(PM,'LON');
PM_val = ncread(PM,'PM25');
S = shaperead('C:\Users\jorda\Desktop\Physics Project\filt_country.shp');
[LAT,LON]=cdtgrid([0.05 0.05]);
strc1 = struct2cell(S);
strc2 = strc1(5,:)';
st = cell2mat(strc2);
i = 1;
while i <= 51
mat_zer=zeros(3600,7200);
isin1 = inpolygon(LON,LAT,S(i).X,S(i).Y);
mat_zer(isin1)=st(i);
[row1,col1] = find(mat_zer~=0);
mat_zer_pm = PM_val;
inds1 = sub2ind(size(mat_zer_pm),row1,col1);
new_mat1 = nan(size(mat_zer_pm));
new_mat1(inds1) = mat_zer_pm(inds1);
Country{i,2} = new_mat1;
i = i + 1;
end

[row1,col1] is the index for mat_zer
in sub2ind(), it is using size(mat_zer_pm)
Do mat_zer_pm and mat_zer have the same size all the time?
