I have 2 matrices path one is path which is 6x2 and sample8 which is 3X3. I want to extract an element from sample8 and put it in path as shown below:
path(i,1)=sample8(1,1)
When I do this I get no change in path Please help

1 1
1 1
1 1
1 1
>> sample8
sample8 =
1 1 1
1 1 1
1 1 1
>> path(i,1)=sample8(1,1)
path =
1 1
1 1
1 1

You are replacing a 1 with a 1. What output were you expecting?

Has i been given a value?
>> path=rand(6,2); sample8=reshape(1:9,3,3)
sample8 =
1 4 7
2 5 8
3 6 9
>> i=2, path, path(i,1) = sample8(1,1)
i =
2
path =
