I am having two matrix. one matrix element represent the position whereas other matrix contine the elements. Now i have to merge these two matrix based on position and to find corresponding element.
for example:
a=[ 5 6 3 7]
b=[011 101 010 001 100 110 111]
expected output:
c=[100 110 010 111]
i need to apply this problem to a larger n*m matrix.

Thank you for your reply. But while applying this condition, only one bit from binary element is displayed as output.
otained output:
0
1
1
1
expected output:
010
100
110
111
