How can i assign a value for this type of datas?

Hi,

I want to assign a value for a given vector with using a one rule. Assigned value will be named as x.

My reference vector is:

[6 5 4 3 2 1]

For ex., given vector is symbolized as A:

A=[NaN NaN 1 1 NaN NaN]

x should be equal to 4.

or if A equals to:

A=[1 1 1 1 1 1]
x=6

Finally, a last example:

A=[NaN NaN NaN 1 1 1]
x=3

Briefly, x value should be equal to leftmost 1's reflection in referance vector.

How can i perform this control?

Thx!

First example is not clear.

[6 5 4 3 2 1]

[NaN NaN 1 1 NaN NaN]

V(find(A==1,1,'first')) % V is your referenced vector

[Alex Yande]

V(find(A,1,'first')) % V is your referenced vector

It works, but give me uncorrect result.

A=[NaN 1 1 1 NaN NaN]
V=[6 5 4 3 2 1]
V(find(A,1,'first'))
ans =
     6

It must be equal to 5.

Your second code works wonderful!!

Thanks a lot.
