Extracting fieldnames and values from a struct and converting to strings

Hello.

I have a struct containing information from a camera configuration (using imaq)

currentConfiguration = 

  struct with fields:

         TriggerType: 'manual'
    TriggerCondition: 'none'
       TriggerSource: 'none'
       

I would like to append all the fields to a UITextArea hence need to extract all the fields as strings. I have tried the following:

                str=sprintf('%s\t', currentConfiguration(1:end));   
                ReportMessage(app,str);   %This is my function to append to a UITextArea

But I get the message

    'Error using sprintf
     Function is not defined for 'struct' inputs.

How do I get the field name and its value all as one string, and for all fields.

thanks

Jason

strjoin(cellfun(@(N,V) N+"="+V, fieldnames(currentConfiguration), struct2cell(currentConfiguration), 'uniform', 0), '\t')

Hi Walter, thanks for your reply.

I got this error

               str=strjoin(cellfun(@(N,V) N+"="+V, fieldnames(currentConfiguration), ...
                   struct2cell(currentConfiguration), 'uniform', 0), '\t') 

    'Error using strjoin (line 53)
     First input must be a string array or cell array of character vectors.

                    str=strjoin(cellfun(@(N,V) N+"="+V, fieldnames(currentConfiguration), ...

strjoin(cellfun(@(N,V) N+"="+V, fieldnames(currentConfiguration), struct2cell(currentConfiguration)), '\t')
