how to merge two separate columns

for example these are the two received datas

    A                                                B
1.82360153236024 - 0.126801069315925i     1.20653532936309 - 1.50070646282491i
-1.09982452450882 - 0.0130131075251623i   -1.27852502409063 + 0.403918513514991i
-1.19419279450858 - 0.444918626354312i    1.64123902289233 - 0.969548607716099i
0.00870454233258119 + 0.499169329261103i 1.22166025616077 - 0.333653674402491i
1.80027359203499 - 1.24444938761865i  -0.280512763757004 + 0.971780515175226i
0.499270646936023 + 0.813353494005082i   -1.19262410799816 - 0.133732758757993i
the size is A=524288x1 ,B=524288x1 complex double
convert it to a single column of size *524288 x 1* complex double

What: "merge two number" means?

[Azzi Abdelmalek]

What: "merge two number" means?

[ashok]

A=received bits of size 524288x1 B=received bits of size 524288x1

while combining into one column using s=[A; B] it becomes 1048576x1 but i need 524288x1

[Azzi Abdelmalek]

when you merge, for example the two numbers 10 and 20, what is the result?

[ashok]

actually the work is transmission of image over a 2x2 mimo channel since it uses two receiving antennas i am receiving two streams of 524288x1 for reconstruction of image i need a total of 524288x1 other wise it shows reshape error

You do not want to "merge" the columns, you want to do a MIMO decoding. See for example
