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

more variant
a1=In(:)';
a1(isnan(a1)) = 0;
out = diff([strfind([0 a1],[0 1])-1;strfind([a1 0],[1 0])])';
