      <title>Interupting Maple not working</title>
      <link>http://www.mapleprimes.com/questions/243736-Interupting-Maple-Not-Working?ref=Feed:MaplePrimes:New%20Questions</link>
      <itunes:summary>&lt;p&gt;I am only occasionally using Maple versions with the new ribon user interface and noticed about 2 weeks ago that I cannot&amp;nbsp;interrupt for loops under these interfaces. For example this one&lt;/p&gt;

&lt;pre class="prettyprint"&gt;
for i to 1000 do
    i^i;
end do&lt;/pre&gt;

&lt;p&gt;I re-run the code today (after installing windows updates) and could interrupt before the screen was filled with output but not after executing the code a second time (without restart).&lt;/p&gt;

&lt;p&gt;Is that reproducible on other installations?&lt;/p&gt;

&lt;p&gt;Are there other commands that cannot be interrupted?&amp;nbsp;&lt;br&gt;
If that is known, are there workarounds?&lt;/p&gt;

&lt;p&gt;Update:&lt;br&gt;
I have restarted Maple and have two worksheets open with the same code. I can repeatedly interrupt in one worksheet but not in other&lt;/p&gt;

      <title>What type of matrix normalisation is this</title>

      <itunes:summary>&lt;p&gt;Could anyone tell me what type of matrix normalisation this is and it it built into Maple? I found this in a paper and Google AI said this is the process of normailsation being used.&lt;/p&gt;

      <itunes:summary>&lt;p&gt;I notice that Maple transactions journal does not publish any new issue ever since March this year. Based on the previous recording it is supposed to publish issue each season. When is it going to promote a new issue? My research is supposed to publish there and I believe I have made some interesting progress and it is of interest to the community.&lt;/p&gt;

      <title>Displaying the unevalated sum of the terms in a list</title>
      <link>http://www.mapleprimes.com/questions/243730-Displaying-The-Unevalated-Sum-Of-The?ref=Feed:MaplePrimes:New%20Questions</link>
      <itunes:summary>&lt;p&gt;Newbie here.&amp;nbsp; If L=[1/2, 1/3, 1/4], how can I display the unevaluated sum of the numerical terms in the list?&amp;nbsp; I don&amp;#39;t want to use sigma notation.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;If L=[x,y,z], I can just do `+`(op(L)) to get x+y+z.&amp;nbsp; I can&amp;#39;t make this work with numbers instead of variables.&amp;nbsp; &amp;nbsp;Maple evaluates and gives me 13/12.&amp;nbsp; I want 1/2+1/3+1/4.&lt;/p&gt;

      <title>Local curve distance sought</title>
      <link>http://www.mapleprimes.com/questions/243729-Local-Curve-Distance-Sought?ref=Feed:MaplePrimes:New%20Questions</link>
      <itunes:summary>&lt;p&gt;For the purpose of practicing with Maple, I have worked on a definite integral in the attached file. I found it on the Internet. According to a side calculation, it can only be calculated using famous special functions or series expansions. That is why I am only interested in the numerical evaluation here. According to auxiliary calculations, it can only be computed using famous special functions or a series expansion. It is known that the series expansion of the antiderivative converges very rapidly. Therefore, for comparison purposes, I calculated the values ​​for integration limits of 10 and 100 instead of infinity. In the first graph, the two result curves appear to coincide perfectly. Is there a way to zoom in locally - like using a magnifying glass - to make the difference in the ordinate values ​​visible?&lt;/p&gt;
