format

问题 I have the following Common Lisp code: (defun micro-read-eval-print () (format t "Micro > ") (let ((form (read-line))))) When I run it, I get the following: CL-USER> (micro-read-eval-print) (m-quote a) Micro > NIL Note that I typed in "(m-quote a)", while the Lisp interpreter output "Micro > NIL". Now, I would have expected these events to happen in the reverse order. I would have expected "Micro > " to have been printed first since the format statement comes first. Why isn't it printed first

问题 I'm trying to output a Matrix: M = [1 20 3; 22 3 24; 100 150 2]; Using: for i=1:3 fprintf('%f\t%f\t%f\n', M(i), M(i+length(M)), M(i+length(M)*2)); end And the output is turning out something like: 1 20 3 22 3 24 100 150 2 Which is obviously not great. How can I get it so the front of integers are padded with spaces? Like so: 1 20 3 22 3 24 100 150 2 Any ideas? Thanks! 回答1: You can use string formatting to allocate specific number of characters per displayed number. For example fprintf('% 5d\n

问题 I have a url (slightly modified) like so: https://ssl.site.com/certificate/123/moo.shoo?type=456&domain=$GH$%2fdodo%20[10%3a47%3a11%3a3316] It doesn't work the way I intend it to when passed straight through to PHP cURL because of the brackets. I managed to run the same URL successfully in the command line like so: curl -g "https://ssl.site.com/certificate/123/moo.shoo?type=456&domain=$GH$%2fdodo%20[10%3a47%3a11%3a3316]" Is there an option (similar to -g, for disabling globbing) that I can
