A couple of other notes here:
* Given an array declaration like `var A: [1..n] [1..3] real;`, there's
been some confusion at points in the language's history about what
indexing a slice expression should do: `A[2..n-1][2]` (in fact, you
may have been involved in some of these conversations in the past?)
Sorry. Silly me. I keep changing between C++ and Chapel for testing. I
have gotten out of that bad C++ habit for my Chapel work.
See below ....
var xcoli : [1..n] real;
for i in 1..n do
{
var R = i..m;
xcoli[R] = x[R][i];
SHOULD BE
xcoli[R] = x[R, i];
// code which always refers to just xcoli[R]
// so as to only use the slice over i..m
}
AND
for i in 1..n do
{
var R = i..m;
var xcolii = x[R][i];
SHOULD BE
var xcoli = X[R, i];
// code can simply refer to xcoli because
// it is by definition the slice over i..m
}
