How to use any2csv - returning "??? Undefined function..."

Hi there,

EDIT: Change from csvwrite to any2csv

I'm very very new to Matlab and have to thank Oleg for pointing out what a struct is but now I am using any2csv.

The layout of my struct contains; cell, double, strings and possibly other variables I don't know of. Here is one of the items from the struct:

>> s(3)

ans = 

                   comm: [1x2 struct]
                 charge: [36x2 double]
                 active: [361x2 double]
               logtimes: [2x1 double]
                     on: [40x2 double]
                   locs: [3195x2 double]
               all_locs: [40x1 double]
                loc_ids: [3195x1 double]
           device_names: {1x6100 cell}
            device_macs: {1x6100 cell}
            device_date: [1x6100 double]
      device_list_names: {1x290 cell}
       device_list_macs: [290x1 double]
           device_types: {1x6100 cell}
      device_list_types: [290x3 double]
              cellnames: {4x2 cell}
                   apps: {1x340 cell}
                 timeon: 14.6830
              app_dates: [1x340 double]
               comm_sms: 0
          comm_sms_date: []
             comm_voice: 2
        comm_voice_date: [2x1 double]
              comm_data: 0
         comm_data_date: []
             surveydata: [1x25 double]
                 my_mac: {'000e6d2a3577'}
           my_startdate: {'8/18/2004'}
               my_affil: {'1styeargrad '}
               my_group: {'sandy'}
              my_office: {'384b'}
                my_plan: {''}
            my_provider: {''}
           my_community: {'a little close'}
               home_ids: 5.1234e+003
         survey_start_n: '24-Jan-2005'
                    mac: 6.1961e+010
             my_minutes: {[NaN]}
             my_enddate: 7.3219e+005
        my_hashedNumber: []
                 places: [1x1 struct]
                   imei: {[NaN]}
           neighborhood: {'Boston'}
               my_hours: {'9am-12pm*'}
             my_regular: {'very'}
            my_hangouts: {'nowhere else'}
         my_predictable: {'very'}
              my_forget: {'occasionally'}
             my_battery: {''}
                my_sick: {''}
        my_sickrecently: {''}
              my_travel: {''}
                my_data: {''}
               my_texts: {''}
              my_intros: {'never'}
            home_nights: [1x12 double]
             comm_local: 2
               data_mat: [24x144 double]

I have never used MATLAB in my life, never been taught how to use etc., which is why I ended up here, I have a large .mat file and I want to take the data out so I can play around with it in Java.

This is attempt at using any2csv and the error:

    >> any2csv(s,',',0,'s.csv')
    ??? Undefined function or method 'any2csv' for input
    arguments of type 'struct'.

Please help me get this file converted over, thank you!

Some people cannot access images on external repositories due to firewall rules etc...

Since code you used is short and the error message too, please post it here (by editing your original post) and format it properly: http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup

>> csvwrite('helloworld.csv',s)

??? Undefined function or method 'real' for input arguments

of type 'struct'.

Error in ==> dlmwrite at 189

str =

sprintf('%.*g%+.*gi',precn,real(m(i,j)),precn,imag(m(i,j)));

Error in ==> csvwrite at 31

dlmwrite(filename, m, ',', r, c);

I just wanted to show everything including the names of the "struct" to make sure I wasn't missing anything out, but thank you!

[Oleg Komarov]

A structure array is a specific data type. In your case you have a non-scalar structure array.

You cannot simply write a structure array to CSV but you can use this submission: http://www.mathworks.com/matlabcentral/fileexchange/19149

Otherwise we need to know which are the fields of the structure and their types (char, double, cell, else...)

[Ryan tracey]

Should I just post what I have found with any2csv or should I create a new topic?

[Oleg Komarov]

You can always update your original post, since this at the moment remains technically unanswered.

Answer 1

[Oleg Komarov]

You need to add the path where you placed any2csv.m

addpath 'c:\something\...'

Or simply change current folder

cd 'c:\something\...'

Then, MATLAB can "see" what is any2csv and use it.

EDIT

I notice that your structure is complex and has many fields of different types and dimension, not sure it will be able to convert everything. In that case post the error you get.
