Hi there I have a large matrix that contains numbers (both positive and negative) and NaN. I need to find the median of this matirx to plot a line.
Doing the median on the whole matrix gives me a value followed by NaNs which I cannot plot as a line.
I have tried the following:
realidx = arrayfun(@isreal,a);
only_reals = a(realidx);
only_real_part = real(a);
but it just gives me lots of 1s. I need the actual values extracting.. I also need all the values to be in one vector other wise all the columns would be of diferent lengths.
Any help would be amazing!
Thanks

A = [1 2 3; NaN -2 0; NaN 5 -8]
result = A(~isnan(A))
gives.
A =
1 2 3
NaN -2 0
NaN 5 -8
result =
1
2
-2
5
3
0
-8
Best regards
