And I am trying to divide into four quadrants starting from a given theta. Say that the index of the given theta is 13 (out of 73), I define my quadrants that are each 90 degrees as follows : </font></div><div class=""><font face="Palatino" size="4" class=""><br class=""></font></div><div class=""><font face="Palatino" size="4" class="">Array : theta [73]</font></div><div class=""><font face="Palatino" size="4" class="">Quadrant 1 : theta(13:31)</font></div><div class=""><font face="Palatino" size="4" class="">Quadrant 2: theta(31:49)</font></div><div class=""><font face="Palatino" size="4" class="">Quadrant 3: theta(49:67)</font></div><div class=""><font face="Palatino" size="4" color="#ff2600" class="">Quadrant 4: theta(67:13)</font></div><div class=""><font face="Palatino" size="4" color="#ff2600" class=""><br class=""></font></div><div class=""><font face="Palatino" size="4" class="">Now, as you’ll notice, having an index of 67:13 doesn’t imply 67:72 and 0:13, it simply implies 13:67 backwards. How do I index the array such that it takes it in a cyclic fashion? For example (what I don’t want is), in a simpler array of just five dimensions : </font><span style="color: rgb(77, 47, 45); font-family: Courier; font-size: 16px; background-color: rgb(237, 234, 212);" class="">Variable: a</span></div><div style="margin: 0px;
