How to save a structure array to a text file

Question

In MATLAB how do I save a structure array to a text file so that it displays everything the structure array shows in the command window?

Answer 1

To convert any data type to a character vector as displayed in the MATLAB command window, use the function

str = matlab.unittest.diagnostics.ConstraintDiagnostic.getDisplayableString(yourArray);

You can then write the contents to a file

fid = fopen('myFile.txt', 'w'); 
fwrite(fid, str, '*char');
fclose(fid);
