Usage

From source file:Util.java

/**
 * Returns an array of indices indicating the order the data should be sorted
 * in. Duplicate values are discarded with the first one being kept. This method
 * is useful when a number of data arrays have to be sorted based on the values in
 * some coordinate array, such as time./*from   w ww .  j  a v a 2s .c  om*/
 *
 * To convert a array of values to a sorted monooic array try: <br>
 *    double[] x;  // some 1-D array of data <br>
 *    int[] i = MathUtilities.uniqueSort(x); <br>
 *    double[] xSorted = MathUtilities.orderVector(x, i);<br><br>
 *
 * @param x An array of data that is to be sorted.
 * @return order An array of indexes such that y = Array.sort(x) and
 * y = x(order) are the same.
