You didn't put but one numeric formatting string in the format; hence, the whole thing repeats as often as needed to output the array. You needs must count the array and build the format string to match:
fmt=['array =' repmat(' %1.0f',1,numel(array))];
fprintf(fmt,array)
NB: The above will echo to screen w/ a newline which may or may not be desired behavior depending upon the application. If want to just display the above on the command line w/ next prompt on new line instead of at end of the string, have to add the \n explicitly:
fmt=['array =' repmat(' %1.0f ',1,numel(array)) '\n'];
One last little nuance: notice didn't put a blank after the '=' sign; that's in front of the numeric format string portion...one after the equal would end up doubling-up for the first element.
