Transpose Matrix in Mathematica

Welcome to the Transpose Matrix in Mathematica page! Here, you'll find the source code for this program as well as a description of how the program works.

Current Solution

(* Code *)

(* This is provided by the Mathematica built-in Transpose; so the only code needed is the 'user interface'
   to make it look a little more like a Unix command-line tool: *)

transposeMain = Function[{columns, rows, values},
   Module[{e = "Usage: please enter the dimension of the matrix and the serialized matrix"},
    Catch[
     StringRiffle[
      Flatten @*
        Transpose @*
        (* convert list of values and dimensions into matrix *)
        Function[{c, r, v},
         If[c*r == Length[v], Partition[v, c], Throw[e]]] @@
       Map[
        (* convert string to integer, or throw *)
        s \[Function] If[StringMatchQ[s, DigitCharacter ..],
          FromDigits[s],
          Throw[e]],
        (* construct three arguments to transpose: number of columns, rows, and list of values *)
        {columns, rows, StringSplit[If[StringLength[values] > 0, values, Throw[e]], ", "]},
        {-1} (* at each leaf *)],
      ", "]]]];


(* Valid Tests *)

Print /@ Apply[transposeMain] /@ {
    {"3", "2", "1, 2, 3, 4, 5, 6"}
    };


(* Invalid Tests *)

transposeMain["", "", "1, 2, 3, 4, 5, 6"]
transposeMain["3", "3", ""]
