Extract all numbers from a matrix that also contains NaN into a single vector

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
