How do I write multiple excel csv files in for loop?

My for loops are as follows;

number of image files are 114

number of shape files are 242

for m = 1:length(imgfiles)

for n = 1:length(shapefiles)

avg_village_ndvi(n,m) = mean(village_ndvi(mask));

avge_village_ndre1(n,m) = mean(village_ndre1(mask));

avg_village_cire(n,m) = mean(village_cire(mask));

CAF(n,m) = nnz(village_ndvi(mask) > 0.4) / (size(village_ndvi,1)*size(village_ndvi,2))

end

end

I want to write these data in seperate excel csv file with file name as 'c:\data\ndvi_predictors.csv','c:\data\ndre1_predictors.csv','c:\data\cire_predictors.csv' and 'c:\data\caf_predictors.csv'.

I request all to please suggest me how to do it in above mentioned matlab code.

I would appreciate any help in this regard.
