How to call files with location names of >1 words?

Dear all,

I am writing an App with AppDesigner. In my Interface, I have several locations that can be chosen, namely Berlin, Amsterdam and Mexico City. In my folder, I have files which are called depending on the location. These files are called temperature_berlin, temperature_amsterdam and temperature_mexicocity. I do have implemented the lower() code, so my programm looks for lower case names. However, I do have the problem that Mexico City is written in two words, so my program does not recognize the according file.

location = lower(app.location.Value);
Struct_temperature = load(['.\data\temperatures\temperature_', location]);
temperature = Struct_temperature.(['temperature_',location]);

The file names are temperature_mexicocity etc.

Writing a file with - such as temperature_mexico-city is not allowed. This would also mean to write the location name in my interface as Mexico-City which is not very pretty.

Could somebody give me a hint?

With kind regards

Gudrun

Build a lookup table of the user name and the associated file names is the quick and dirty way...the somewhat cleaner but takes a little more code is to write a set of functions that translate to/from the actual user city name to the associated file name.

You can of course, even use "Mexico City Temperature.dat" as a file name if you make sure your app always quotes it. I don't recommend just for ease of coding to do so, but the OS will allow it.

You can delete all spaces with the command

strrep(str, ' ', '')

Then

location = lower(strrep(app.location.Value, ' ', ''));
Struct_temperature = load(['.\data\temperatures\temperature_', location]);
temperature = Struct_temperature.(['temperature_',location]);

You can use the following:

>> location = lower(fname);            % convert to lower case
>> location = char(location);          % convert to char array (rather than string)
>> location = location(location~=' ')  % remove spaces if any exist
>> location = location(location~='-')  % remove hyphens if any exist (as in Winston-Salem)

location =

    'mexicocity'
