How to aggregate two columns
显示 更早的评论
I want to combine two columns. Here is the example of probleme: A column has lot of number like 20100101;20100102... .B column has the same amount of numbers like 020510000;020510040... . I want to aggregate A and B columns to have one column like 2010010120510000;20100102020510040... . That every A(x) would be in the same row with B(x). Thank you very much.

One approach:
A = [20100101;20100102];
B = [020510000;020510040];
ABS = sprintf('%d%09d\n', [A, B]'); % String Representation
ABN = str2num(sprintf('%d%09d\n', [A, B]')) % Numeric Conversion

This is how one would do it if A and B are doubles:
C = A*1e8 + B;
However, each of A and B has 8 decimal digits, so the result of this calculation will have 16 decimal digits. That is right at the limit of what a double precision value can hold, and may even be beyond depending on the actual values involved. So this might not work and you may need a different method.
If A and B are actually char arrays, then it is simply:
C = [A,B];
