MATLAB: Count number of values between NaN

Question

Hello,

I have data set that looks something like this:

NaN; NaN; NaN; NaN; 1; 1; 1; 1; NaN; NaN; NaN; 1; NaN; NaN; NaN; NaN; NaN; NaN; NaN; 1; NaN; NaN; NaN; NaN;

I need to produce a vector of the numbers of 1's between each set of NaNs.

For example with the above data my vector would look like this:

4;1;1

Any suggestions would be greatly appreciated!

Thanks, Dan

In = [NaN; NaN; NaN; NaN; 1; 1; 1; 1; NaN; NaN; NaN; 1; NaN; NaN; NaN; NaN; NaN; NaN; NaN; 1; NaN; NaN; NaN; NaN];
[a,b] = rude(~isnan(In));
a(b)

rude is on the FEX
