Description. fprintf (fileID,formatSpec,A1,...,An) applies the formatSpec to all elements of arrays A1,...An in column order, and writes the data to a text file. fprintf uses the encoding scheme specified in the call to fopen. example.

You needs must count the array and build the format string to match: fmt= ['array =' repmat (' %1.0f',1,numel (array))]; fprintf (fmt,array)
I have a vector x = (1, 2, 3) and I want to display (print) it as Answer: (1, 2, 3). I have tried many approaches, including: disp('Answer: ') strtrim(sprintf('%f ', x))
The fprintf function is vectorized for nonscalar arguments. The function recycles the format string through the elements of A (columnwise) until all the elements are used up. The function then continues in a similar manner through any additional matrix arguments.
(B.1) Using fprintf( ) with arrays: If you only specify one formatting command, all elements of an array will be printed on a single row (even multidimensional arrays). For multidimensional arrays, elements will be printed off one column at a time. M-file: x = (1 : 0.25 : 2) y = [1,4,7 ; 9,8,6]; fprintf('%7.2f' , x) fprintf('\n')
Sometimes the ability to output a single value is adequate, but the ability to describe values and the ability to output entire matrices and arrays are more useful. Consider fprintf: fprintf(ID, 'Format text and conversion characters', variable matrix); The second argument is not limited to conversion characters.
