What is the difference between [@] and [*] when referencing bash array values? says:  If the index number is @ or *, all members of an array are referenced.  When I do this: LIST=(1 2 3) for i in &quot;${LIST[@]}&quot;; do   echo &quot;example.$i&quot; done  it gives the desired result: example.1 example.2 example.3  But when I use ${LIST[*]}, I get example.1 2 3  instead. Why? Edit: when using printf, @ and * actually do give the same results. Proving convergence of sums: If $\sum_{n=1}^{\infty}a^2_n$ and $\sum_{n=1}^{\infty}b^2_n$ converge then $\sum_{n=1}^{\infty}a_nb_n$ converges How do I import a dxf? I am a noob with blender.

I went to the Italian consulate in Washington, DC today and they would not accept my visa application because they said my US visa stamp cannot expire less than 3 months after the end of my trip to Italy. Here's my relevant visa and trip info:   US visa stamp expires on 16 Dec 2015 I-797 valid until 3 Mar 2017 Trip to Italy is from 15 Oct to 25 Oct 2015   Is it true that my visa stamp needs to be valid for 3 months after my trip, even though I can legally stay in the US until 2017? Does anyone have any suggestions for getting a Schengen visa in my situation? Difference between "should" and "must" What is the difference between "should" and "must"?  e.g. "They should have called the police."

I just added a PPA repository for the development version of the GIMP, but I get this error:  $ apt-get update &amp;&amp; apt-get upgrade ...

Prove that $R/Ra$ is an injective module over itself.   If $R$ is a PID, every $R$- divisible module is injective, but the question concerns with $R/Ra$-module, so I have no idea to solve this problem. Help me. When does SQLiteOpenHelper onCreate() / onUpgrade() run? Wiener Process $dB^2=dt$ Why is $dB^2=dt$? Every online source I've come across lists this as an exercise or just states it, but why isn't this ever explicitly proved? I know that $dB=\sqrt{dt}Z$, but I don't know what squaring a Gaussian random variable means. Answer appears automatically converted as a comment gdal.VectorTranslate returns an empty file I have read this topic:   There, the issue is handling two different generations of PHP (PHP 4 vs PHP 5), but what I need is to make all but one of my server accounts work under 5.3 and just a single domain under 5.2.  I cannot make this through Apache models, and the answer from  does not apply since in my case I can't use a different port - this is a regular website  on the same server.

Array of Matrices in MATLAB I am looking for a way to store a large variable number of matrixes in an array in MATLAB.  Are there any ways to achieve this?  Example:  for i: 1:unknown   myArray(i) = zeros(500,800); end   Where unknown is the varied length of the array, I can revise with additional info if needed.  Update: Performance is the main reason I am trying to accomplish this.  I had it before where it would grab the data as a single matrix, show it in real time and then proceed to process the next set of data.  I attempted it using multidimensional arrays as suggested below by Rocco, however my data is so large that I ran out of Memory, I might have to look into another alternative for my case.  Will update as I attempt other suggestions.  Update 2:  Thank you all for suggestions, however I should have specified beforehand, precision AND speed are both an integral factor here, I may have to look into going back to my original method before trying 3-d arrays and re-evaluate the method for importing the data.
