Variable Documentation

seq span

Reference entire dimension.

The span operator is used to specify the indexing to use the entire dimension. It is equivalent to doing the following:

seq(0, end)

seq(0, dims(x) - 1), where x is 0, 1, 2, or 3.

The span operator is very useful in subscript indexing.

float hA[] = { 0,1,2,3,4,5 };
array A(2,3,hA);
A(span,1) // reference second column: {2 3}
A(span)   // entire array flattened as column vector
