Thread Subject: array question

Hello
I have this particular type or array,example

a = [0 0.0360 NaN NaN NaN 0.0040 0.0530 NaN NaN NaN NaN 0.0080 NaN NaN ]
Now I want the array b such that
b = [0 0.0040 0.0080] and its indices as well such that
index = [1 6 12]
so on and so forth
My main aim is to get only the first numeric value in between the 2 NaN's, if there are 2 or more numeric values in between the NaN's I want to ignore them
How do I achieve this?

Thanks

Vihang

something like this?
b = a(diff(isnan([NaN,a,NaN]))==-1)

Hello
Thanks, can you tell me how do I get the indices of the same..

Another way:
ind = strfind([true isnan(a)],[1 0])
