How to join many columns of data in array?
Multi tool use
$begingroup$
I have large number of columns of data. How to put in single matrix?
For example, with test data of 1 x 3 matrixs
test[1] = {1, 1, 1}
test[2] = {2, 2, 2}
test[3] = {3, 3, 3}
test[4] = {4, 4, 4}
I use
Array[test, 4, 1, Join]
and get 1 x 12 matrix
{1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4}
I want to get 4 x 3 matrix
{{1, 2, 3, 4}, {1, 2, 3, 4}, {1, 2, 3, 4}}
list-manipulation matrix array

You can try creating an Array
and then Transposing:
In[14]:= Transpose @ Array[test, 4]
Out[14]= {{1, 2, 3, 4}, {1, 2, 3, 4}, {1, 2, 3, 4}}
$endgroup$

$begingroup$
num = 4;
test[#] & /@ Range[num] // Transpose
{{1, 2, 3, 4}, {1, 2, 3, 4}, {1, 2, 3, 4}}

Another possibility:
Array[List /@ test[#] &, 4, 1, Join[##, 2] &]
$endgroup$

$begingroup$
Array[test, 4, 1, Transpose[{##}] &]
{{1, 2, 3, 4}, {1, 2, 3, 4}, {1, 2, 3, 4}}
also
Array[test, 4, 1, Flatten[{##}, {2}] &]
Array[test, 4, 1, Thread[{##}] &]

You can try creating an Array
and then Transposing:
In[14]:= Transpose @ Array[test, 4]
Out[14]= {{1, 2, 3, 4}, {1, 2, 3, 4}, {1, 2, 3, 4}}
