c# 3.0 - How to make double[,] x_List in C#3.0? -

-

i ned implement multi-linear regression in c#(3.0) using linest function of excel. trying achieve 

=linest(acl_returns!i2:i10,acl_returns!j2:k10,false,true)

so have data below

double[] x1 = new double[] { 0.0330, -0.6463, 0.1226, -0.3304, 0.4764, -0.4159, 0.4209, -0.4070, -0.2090 }; double[] x2 = new double[] { -0.2718, -0.2240, -0.1275, -0.0810, 0.0349, -0.5067, 0.0094, -0.4404, -0.1212 }; double[] y = new double[] { 0.4807, -3.7070, -4.5582, -11.2126, -0.7733, 3.7269, 2.7672, 8.3333, 4.7023 };

i have write function signature be

compute(double[,] x_list, double[] y_list) {    linest(x_list,y_list, true, true); < - excel function call. }

my question how using double[] x1 , double[] x2 make double[,] x_list ?

i using c#3.0 , framework 3.5.

thanks in advance

actually should be

double[,] xvalues = new double[x1.length, x2.length]; int max = (new int[]{ x1.length,x2.length}).max(); (int = 0; < max; i++) { xvalues[0, i] = x1.length > ? x1[i] : 0; xvalues[1, i] = x2.length > ? x2[i] : 0; }

samir right, should call max() once outside iterator rather each iteration, i've amended this.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (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...

php - Replacing tags in braces, even nested tags, with regex -

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."
