Crossover applications in matlab

I want to apply crossover betweem x1 and x2

x1=[ -1.0000 - 1.0000i 2.0000 - 2.0000i 3.0000 - 3.0000i];

x2=[ -4.0000 - 4.0000i 5.0000 - 5.0000i 6.0000 - 6.0000i];

CrossoverIndex=1;

>> c2 = [x2(1:CrossoverIndex) x1(CrossoverIndex+1:end)];

But i found this error:

Error using horzcat

Dimensions of matrices being concatenated are not consistent.

Can any one help me how can i solve the error.

you show x1 and x2 as row vectors but your code is p1 and p2. If p1 and p2 are column vectors you would have problems with your [] operation if the crossover was not exactly half way . II suspect you should use ; between the parts.

I have corrected the question .

[Walter Roberson]

command

dbstop if error

then run the code. when it stops show size(x1) and size(x2)

Thank you very much, the problem is solved if using the transpose operation :

c2 = [x2(1:CrossoverIndex)' x1(CrossoverIndex+1:end)'];

Walter Roberson,do you know why solved by add the transpose operation ?

[Walter Roberson]

If the code you posted were the only code that were in place, then it would have been correct. I suspect that you are passing those values into a function that is transposing them.
