MATLAB: How to combine multiple files into one .csv

If I run your code and pause it after the first execution of the for loop, the num variable is empty, so something might be up with the file formats? At least, it explains why you only get the first file out, as you append empty arrays to your first file every loop.

I assume you want the header from the first file + the numeric data from the first and second files printed out? This does the trick, although I shudder at the file format ;) it should also work if your input is 100 files instead of 2.

filenames={'C:\PhD\Projects\LIFE ASTI\C.3\WRF_main_TS_2015_ALL\WRF_Times_ALB+EMISS_FINAL2015\WRF_Thessaloniki_stations_2015\Tapp\Airport\Hourly_Stats Airport Tapp .csv','C:\PhD\Projects\LIFE ASTI\C.3\WRF_main_TS_2015_ALL\WRF_Times_ALB+EMISS_FINAL2015\WRF_Thessaloniki_stations_2015\Tapp\Eptapurgio\Hourly_Stats Eptapurgio Tapp .csv'};
filenames = filenames.';
[~,~,RAW]=xlsread(filenames{1});
for i=1:size(filenames,1)
[~,~,all]=xlsread(filenames{i});
RAW{i+1}=all{2}; 
end
xlswrite('C:\PhD\Projects\LIFE ASTI\C.3\WRF_main_TS_2015_ALL\WRF_Times_ALB+EMISS_FINAL2015\WRF_Thessaloniki_stations_2015\Tapp\CombinedFile.csv',RAW)

MATLAB: Am I receiving errors when I change one of the virtual buses into a nonvirtual bus using Simulink

This enhancement has been incorporated in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

When converting to a nonvirtual bus, all buses feeding the bus creator must have bus objects defined for them. Also if the bus you want to convert then feeds a bus creator block, that block must also output a nonvirtual bus. It is not possible to have nested buses of mixed type, virtual or nonvirtual.

Once all buses are converted appropriately, a valid update diagram will occur.

One can follow these steps in the conversion process:

1. Update the model containing the virtual buses

2. Identify bus (BUS_X) that will become non-virtual

3. Generate bus objects for that bus and all bus creators up stream from that Bus Creator

4. Populate bus objects for all bus creators upstream and the bus creator associated with BUS_X

5. Set Bus Creator associated with BUS_X to ‘output as nonvirtual’

6. Identify all Bus Creator blocks that BUS_X feeds

7. Identify all Buses to that Bus creator

8. Make sure all Buses are nonvirtual (make bus objects and set to nonvirtual for each)

9. Make the output of that Bus Creator nonvirtual (by creating bus objects)

10. Recursively do step 5 until no more Bus Creators are found, leaving behind only Bus Selectors.

11. Update diagram once again to make sure that the conversion has been successful.
