Brett<\/a>'s Pick this week is \"Random Face Generator\"<\/a>, by Joseph Hollmann<\/a>.\r\n <\/p>\r\n

I wrote today's post in advance. I fully expect that, when this goes live on Friday morning, I will be sitting on a tropical\r\n beach in the Dominican Republic, sipping umbrella drinks and contemplating the crystal clear cerulean water.\r\n <\/p>\r\n

So, in the spirit of Spring Break and focusing on family fun, a bit of frivolity for today's Pick.<\/p>\r\n

Joseph's submission doesn't really do anything of a practical nature, but it does<\/i> make you smile. As he says in the preamble to his code, randomfacegenerator<\/tt> \"generates a randomly created face and plots it....nothing else.\"\r\n <\/p>\r\n

I have one suggestion for improvement. Calling the figure<\/tt> command in the function is probably unnecessary; you can easily end up with many open figures before you know it. I would\r\n suggest replacing the lines:\r\n <\/p>

figure;\r\nset(gcf,'name'<\/span>,'Your New Face'<\/span>);<\/pre>
with a call to togglefig<\/tt><\/a>:\r\n   <\/p>
togglefig('Your New Face'<\/span>)<\/pre>
(That is, if a figure named \"Your New Face\" exists, activate and reuse it. Otherwise, create it.) No inputs required:<\/p>
while<\/span> ~strcmp(get(gcf,'currentcharacter'<\/span>),'s'<\/span>)\r\nrandomfacegenerator\r\npause(0.5);\r\nend<\/span><\/pre>
 <\/p>\r\n   
Thanks for putting me in vacation mode a day early, Joseph!<\/p>\r\n   
 <\/p>\r\n   
As always, I welcome your thoughts and comments<\/a>. Or leave feedback for Joseph here<\/a>.\r\n   <\/p>
