How to include current array from multiple for loops into csvwrite filename

I have the following for loop within a for loop:

for lat = [1.5,2,3.5]    
   for lon = [1,2.5,3]
       for year[1990:2019]
       (stuff happens)
       end
       csvdata=[var1,var2,var3]
       csvwrite(lat lon.csv, csvdata)
   end
end

each output of the lon loop needs to be stored in a seperate file, I would like the CSV file name to be the lat and lon of the current loop so that the csv does not keep overwriting. I do not want to append.

I do not know if it is worth noting that the lat and lon numbers contain decimals.

I have struggled with various things but cannot seem to get it to work. I am new to matlab so appreciate this may be a messy way of doing what I want to do.

Thanks in advance for any help!

Hi, try this command instead

csvwrite([num2str(lat),'_',num2str(lon),'.csv'], csvdata)
