How to remove NaNs from an array between points

Question

0 个投票

example.mat

I have an array consisting of real numbers and NaNs. I'd like to identify the first row where there is a real number, then extract data from that point to when the next NaN occurs. If you see the attached example, I'd like the results to be example(17:43).

Thanks to the community for the help and let me know if I can cleary anything up!

Sorry - one more item: I'd like the Nans before the first real number row to remain intact - this would mean the results are example(1:43)

Read about isnan.

idx = isnan(example);
idr = diff(find([1;diff(idx);1]));
D = mat2cell(example,idr(:),size(example,2));
celldisp(D)

Thanks, KSSV. It appears the length(D) ~= example(17:43) - any ideas?
