How to combine two matrix based on position and find the corresponding element?

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.

c = b(a)

Note: This works on your example, because a acts as a linear index into b. It unclear how to generalize what you need for a two-dimensional array.

Also, it is somewhat unclear what b represents. It seems that you are trying to encode something binary, but ...

b=[011 101 010 001 100 110 111]

b = 1×7

11 101 10 1 100 110 111

loses the leading zeros.

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
