Hello,
I have a list {1,2,3,4,5} and I need split this into exactly 4 parts/sublists. One approach was to use Multicolumn[] function. Check this program.
Table[Multicolumn[{1, 2, 3, 4, 5}, n], {n, 1, 5, 1}]
For n=3 and n=4, its resulting in the same output. However, I am expecting the program to split it into 4 columns. Kindly help.
The number of columns depends on the number of data in you list. The 5th column exist , it is just empty because in your dataset does not produce enough points to fill the column. Look at this
Table[Multicolumn[{1, 2, 3, 4, 5}, n], {n, 1, 5, 1}]
Table[Multicolumn[{1, 2, 3, 4, 5, 6}, n], {n, 1, 5, 1}]
Table[Multicolumn[{1, 2, 3, 4, 5, 6, 7}, n], {n, 1, 5, 1}]
Table[Multicolumn[{1, 2, 3, 4, 5, 6, 7, 8}, n], {n, 1, 5, 1}]
Column does the follow ‘calculation’: Let’s say you have n elements and you request c columns:
rows = Ceiling[n/c]
so in your case Ceiling[5/4]=2 rows. So it start creating each column by taking 2 elements each time:
{{1,2},{3,4},{5}}
which is ‘transposed’ and then shown in a grid.
I’m also not sure how you would expect it to outcome for the case of 4?
1345
2
would be very weird! One would put it in a grid like that:
135
24
reads more naturally…
