Hi guys,
I have this table:
Date var_1 var_2 var_3 var_4 var_5 var_6
01-01-90 0.2 0.34 0.43 0.12 0.18 0.1
01-01-91 0.3 0.54 0.53 0.62 0.38 0.2
01-01-92 0.7 0.40 0.77 0.42 NaN 0.2
01-01-93 0.7 0.40 0.77 0.42 NaN 0.2
How do I replace the NaN values in the table with the median of the row for each row?
The result for this table should be:
Date var_1 var_2 var_3 var_4 var_5 var_6
01-01-90 0.2 0.34 0.43 0.12 0.18 0.1
01-01-91 0.3 0.54 0.53 0.62 0.38 0.2
01-01-92 0.7 0.40 0.77 0.42 Med_Row 0.2
01-01-93 0.7 0.40 0.77 0.42 Med_Row 0.2

m = TablE{:,2:end};
ix = any(isnan(m),2);
mix = m(ix,:);
m1 = median(m(ix,:),2,'omitnan') .* isnan(m(ix,:))
m1(m1==0) = mix(~isnan(mix));
m(ix,:) = m1
TablE{:,2:end} = m

1) converting table to a matrix
2) detecting which rows of matrix has nans in it
3) saving those twos of matrix in a variable called mix
4) calculating median for those rows and assigning it to the matrix where nana occurs
5) copying the values other than nan
6) replacing those rows to the original matrix
7) converting it back to a table
