alibThreshold
Thresholds an array.
Prototype
void alibThresholdl( wvlong n, wvlong p, wvlong q, wvlong *i )
Parameters
n — (Input) The number of elements in the array to be thresholded.
p — (Input) The lower threshold.
q — (Input) The upper threshold.
*i — (Input/Output) The array to be thresholded. On return, elements less than p have been set to p and elements greater than q have been set to q.
Example
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include "alib.h"
void main() { /* make up some data for the example */
wvlong b[128];
alibinit( NULL, NULL, NULL, NULL );
alibIndexl( 128, -32, 1, b );
printf( "\n\n show (16,8) array b" );
alibPrintArrayl( 1, 1, 16, 8, b, "%8lld" );
printf( "\n\n threshold b into the range [0,63]" );
alibThresholdl( 128, 0, 63, b );
alibPrintArrayl( 1, 1, 16, 8, b, "%8lld" );
}
Output:
show (16,8) array b
