例句與造句

1. This made Lisp arithmetic comparable in speed to Fortran for scalar operations ( though Fortran array and loop implementation remained much better ).
2. This is because the tape then comprises vector operations; this can facilitate computationally efficient implementations where each vector operation performs many scalar operations.
3. Some decades ago, the runtime-system ( no garbage collection, etc . ), basically supports only scalar operations, and provides direct memory addressing.
4. As well as the addition and multiplication by scalar operations which arise from the vector space structure, there are several other standard operations defined on differential forms.
5. Although such techniques were not widely used by commercial interpreters, they exemplify the language's best survival mechanism : not specifying the order of scalar operations or the exact contents of memory.
6. It's difficult to find scalar operation in a sentence. 用scalar operation造句挺難的
7. In October 2006, an upgraded SX-8 was announced, the SX-8R . The NEC SX-8R processors run at 2.2 GHz for vectors and 1.1 GHz for scalar operations.
8. The processor had forty-eight 32-bit registers, a huge number for the time . 16 of the registers were used for addressing, 16 for scalar operations, 8 for index offsets, and 8 for specifying the various parameters for vector instructions.
9. By replacing the left-hand variant by the right-hand expression, costs shrink from three ( costly ) array traversals to two array traversals plus one ( cheap ) scalar operation ( see Figure, which uses the rasdaman query language introduced before ).
10. This is the reason why ZPL achieves such good performance : having no parallel directives or other forms of explicit parallelism, ZPL exploits the operational trait that when aggregate computations are described in terms of arrays, many scalar operations must be ( implicitly ) performed to implement the array operations.
11. However, marking vectors ( with a small arrow, or a boldface font, or a squiggle, or whatever you want to use ) can be helpful especially when they're used in expressions with scalar quantities to make sure that you only perform vector operations on vectors and scalar operations on scalars.
12. so if the gradient is already computed, the approximate Hessian can be computed by a linear ( in the size of the gradient ) number of scalar operations . ( While simple to program, this approximation scheme is not numerically stable since has to be made small to prevent error due to the term, but decreasing it loses precision in the first term .)
