end VectorTest;
both cause an assertion to fail in the C runtime:
Assertion failed: j == dest->ndims, file real_array.c, line 358
Note:
See TracTickets
for help on using tickets.
It seems the index_spec for xxx := p[1:3] is [{1,2,3}], and that index_spec will reduce the dimensions of the matrix p (which is a vector, dim=1), by 1. This is the fault. From my naive point of view, the dimensions of the result should be the addition of A, W and S*; not the subtraction of A,W from the original dims...
If I remove some assertions from the C runtime, the code does run just fine. Which is weird; someone made the assertions for a reason...
