Scilab help >> Statistics > Data with Missing Values > nanmedian


median of the values of a numerical vector or matrix

Calling Sequence

m=nanmedian(x,'r') (or m=nanmedian(x,1))
m=nanmedian(x,'c') (or m=nanmedian(x,2))



real or complex vector or matrix


For a vector or a matrix x, [m]=nanmedian(x) returns in the vector m the median of the values (ignoring the NANs) of vector x.

[m]=nanmedian(x,'r') (or, equivalently, [m]=nanmedian(x,1)) are the rowwise medians. It returns in each position of the row vector m the medians of data (ignoring the NANs) in the corresponding column of x.

[m]=nanmedian(x,'c') (or, equivalently, [m]=nanmedian(x,2)) are the columnwise madians. It returns in each position of the column vector m the medians of data (ignoring the NANs) in the corresponding row of x.

In Labostat, NAN values stand for missing values in tables.
