Calling Sequence
q=iqr(x) q=iqr(x,'r') (or, equivalently, q=iqr(x,1)) q=iqr(x,'c') (or, equivalently, q=iqr(x,2))
Arguments
x
real or complex vector or matrix
Description
This function computes the interquartile range IQR= upper quartile - lower quartile of a vector or a matrix x.
For a vector or a matrix x , q=iqr(x) returns in the scalar q the interquartile range of all the entries of x.
q=iqr(x,'r') (or, equivalently, q=iqr(x,1)) is the rowwise interquartile range. It returns in each entry of the row vector q the interquartile range of each column of x.
q=iqr(x,'c') (or, equivalently, q=iqr(x,2)) is the columnwise interquartile range. It returns in each entry of the column vector q the interquartile range of each row of x.
