matlab - How should I write a matrix onto a text in Hex format? -


i have matrix, say:

m = [1000 1350;2000 2040;3000 1400];

i wish write matrix onto text file in hex format, this:

0x000003e8 0x00000bb8   0x000007d0 0x000007f8    0x00000bb8 0x00000578

i considered using function dec2hex it's slow , inefficient. gives me output string, don't know how restructure above required format.

matlab directly converts hex numbers decimal when reading text file, ex. when using function fscanf(fid,'%x').

can exact same thing while writing matrix?

you can use %x format string. sake of demonstration, see example sprintf below. if want write file, have use fprintf. 

m = [1000 1350;2000 2040;3000 1400]; str = sprintf('0x%08x\t0x%08x\n', m')

this results in

str =  0x000003e8  0x00000546 0x000007d0  0x000007f8 0x00000bb8  0x00000578

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/...
