macro in node option












1















I use pgfkeys of tikz to define something(please see the following MWE), but the simple code can not compile.I guess wrong way of using the macro ifthenelse in pgfkeys is the cause. But why?



documentclass{article}

usepackage{tikz,ifthen}

begin{document}



pgfkeys{%

    tp/.code=deftp{%

      ifthenelse{equal{#1}{}}%

        {centered}%

        {above=#1}%

      },

      tp/.default={},

      mydraw/.code={tikzdraw(0,0)--node[#1]{node}(1,0);}

  }

pgfkeys{tp,mydraw/.expanded={tp}}



end{document}

          count number of partitions of a set with n elements into k subsets

          up vote 6 down vote favorite 1 This program is for count number of partitions of a set with n elements into k subsets I am confusing here return k*countP(n-1, k) + countP(n-1, k-1); can some one explain what is happening here? why we are multiplying with k? NOTE->I know this is not the best way to calculate number of partitions that would be DP // A C++ program to count number of partitions // of a set with n elements into k subsets #include<iostream> using namespace std; // Returns count of different partitions of n // elements in k subsets int countP(int n, int k) { // Base cases if (n == 0 || k == 0 || k > n) return 0; if (k == 1 || k == n) return 1; // S(n+1, k) = k*S(n, k) + S(n, k-1) return k*countP(n-1, k) + countP(n-1, k-1); } // Driver program int ma

          A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

          Image
          0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
