Return the interquartile range, i.e., the difference between the upper and lower quartile of the input data.
If x is a matrix, do the above for first non-singleton dimension of x.
If the optional argument dim is given, operate along this dimension.
As a measure of dispersion, the interquartile range is less affected by
outliers than either range
or std
.
