<div class="">Hi Dennis, </div>
<div class=""><br class="">
</div>
<div class="">I will work on coding up the suggested algorithm…</div>
<div class="">However, it might be easier to rephrase the question:</div>
<div class=""><br class="">
</div>
<div class="">I have an array of HI(time), T(time), and RH(time).</div>
<div class="">I want to qsort(HI), then reorder T and RH to match qsort(HI).</div>
<div class=""><br class="">
</div>
<div class="">Is there a way to do that? </div>
<div class="">Because I can simply use index numbers, and get around this issue.</div>

<div class="">For a sort variation, you might try <a href="https://www.ncl.ucar.edu/Document/Functions/Built-in/dim_pqsort_n.shtml" target="_blank" class="">
<b class="">dim_pqsort_n</b></a> which is from the fortran <a href="https://www.netlib.org/slatec/guide" target="_blank" class="">
<b class="">SLATEC </b></a>library.</div>
<div class=""><br class="">
</div>
<div class="">NCL's <b class="">dim_pqsort_n </b>should be able to handle any dimension size.</div>
<div class=""><br class="">
</div>
<div class="">Under-the-hood: To my knowledge, fortran's default integer type is 32-bits [ 4 bytes ] =>
<span class="gmail-ILfuVd">2,147,483,647 <br class="">
</span></div>
<div class=""><span class="gmail-ILfuVd">NCL's C-interface checks the size of the dimension being sorted. I it exceeds the 32-bit size, NCL uses a special version that allows [64-bit; 8-byte; INTEGER*8] indexing.<br class="">

<div class="">Hi Rick,</div>
<div class=""><br class="">
</div>
<div class="">I am running into an issue where I have some repeat values. Is there a way to add a precision level adjustment during the qsort algorithm? </div>

<div class="">Hi Jonathan -- yes, qsort() takes a double, or more generally a "numeric" type.</div>

Hello NCL-Talk,<br class="">
<br class="">
Does qsort operate at double precision?<br class="">
I am trying to resolve my stat_dispersion issue by isolating the problem...<br class="">
