minFractof

MINFRACTOF Extract value at the Nth percentile.

[ VALUE_AT_PERCENTILE, SORTED_DATA ] = minFractof( DATA, PERCENTILE, ORDER)
MINFRACTOF Extract data value at the Nth percentile of the data sample.

V = MINFRACTOF(D) extract 75%tile of D.
V = MINFRACTOF(D,P) extract P%tile of D.
V = MINFRACTOF(D,P,O) extract ascending of descending P%tile of D. See
SORT options ASCEND and DESCEND.

When D in a matrix, one value is extracted for each column. NaN are not
considered in percentage calculations.

Example

N=[NaN 1];
minFractof( N(fix(rand(100,10)+0.5)+1).*rand(100,10) )
