how can i eliminate this error..

key=[1 0 1 0 0 0 0 0 1 0]
P10=[3 5 2 7 4 10 1 9 8 6]
left=key(P10(1:5))
right=key(P10(6:10))
left_1=circshift(left,[1 -1])
right_1=circshift(right,[1 -1])
bit=bitconcat(left_1,right_1);

i am getting error--

Undefined function 'bitconcat' for input arguments of type 'double'.

Error in bit=bitconcat(left_1,right_1);

bitconcat applies only to fi() objects, not to regular numeric values.

Have you considered just

[left_1, right_1]
