now whats the best way of array indexing them into a doubly linked list. im assuming ill need 3 arrays, and index/next/ and prev. any hints? Upvote 0 Downvote Jan 28, 2010 Thread starter #14 Mercfh Programmer Oct 26, 2009 13 US crap modula didnt work this code does work using...

Note also that indexing such an array is reversed in Fortran and C, andindexing is also different (starting with 1 in Fortran and 0 in C), e.g. REAL:: B(10,5) B(7,3) <-> *(b + (3-1)*10 + (7-1)) <-> b[2][6] Jugoslav Translate 0 Kudos Copy link Reply tkhandan...
In the following code example, you see the main computational kernel that updates the temperature on a 2D grid of points. It usesDO CONCURRENTloops to step through the 2D iteration space using the combined indexing capability ofDO CONCURRENTas described earlier. This expresses more parallelism and...
Generate correct values for a PARAMETER array whose element values are computed in an implied DO loop involving indexing into another PARAMETER array. Correct bad parse of .NE. as record field name. Allow a dummy argument that has an INTENT attribute specified to be specified in a NAMELIST ...

• definitions of functions returning array-valued expressions; • permutations of array indices allowing dimensionindependent definitions of unctions (see e.g. listings C.12 and C.13, P.10 and P.11, F.11 and F.12); • fractional indexing of arrays corresponding to employment of a stag...
