matlab - How do you concatenate the rows of a matrix into a vector? -

-

for m-by-m (square) array, how concatenate rows column vector size m^2 ?

there couple of different ways can collapse matrix vector, depending upon how want contents of matrix fill vector. here 2 examples, 1 using function reshape , 1 using colon syntax (:):

>> m = [1 2 3; 4 5 6; 7 8 9];  %# sample matrix >> vector = reshape(m.',[],1)  %# collect row contents column vector  vector =       1      2      3      4      5      6      7      8      9  >> vector = m(:)  %# collect column contents column vector  vector =       1      4      7      2      5      8      3      6      9

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
