The code assumes a two-dimensional computational domain with TMz polarization (i.e., non-zero field Ez, Hx, and Hy). The program is currently written so that the incident field always strikes the lower-left corner of the total-field region first. (If you want a different corner, that should be a fairly simple tweak to the code, but for now you ll have to make that tweak yourself.) I have attempted to provide copious comments in the code and hope that a knowledgeable C programmer can quickly map the approach as described in the paper to what is in the program.

Many many developers all over the net respect NASM for what i s - a widespread (thus netwide), portable (thus netwide!), very flexible and mature assembler tool with support for many output formats (thus netwide!!). Now we have good news for you: NASM is licensed under LGPL. This means its development is open to even wider society of programmers wishing to improve their lovely assembler. The NASM project is now situated at SourceForge.net, the most famous Open Source development center on The Net. Visit our development page at http://nasm.2y.net/ and our SF project at http://sf.net/projects/nasm/

提出了一種基于樣本的分級檢索 MPEG 視頻的新方法:首先用I 幀的dct_dc_size 字段快速粗檢,然后用斷層攝影(tomography)法分析B 幀運動矢 量的時空分布特性以進一步縮小結果集,最后用DC 圖像的精確匹配方法驗證檢索結果.試驗結果表明,本方法 所需計算量較小,且可保證較高的檢索精度.

算法介紹 矩陣求逆在程序中很常見,主要應用于求Billboard矩陣。按照定義的計算方法乘法運算,嚴重影響了性能。在需要大量Billboard矩陣運算時,矩陣求逆的優(yōu)化能極大提高性能。這里要介紹的矩陣求逆算法稱為全選主元高斯-約旦法。 高斯-約旦法(全選主元)求逆的步驟如下: 首先,對于 k 從 0 到 n - 1 作如下幾步: 從第 k 行、第 k 列開始的右下角子陣中選取絕對值最大的元素,并記住次元素所在的行號和列號,在通過行交換和列交換將它交換到主元素位置上。這一步稱為全選主元。 m(k, k) = 1 / m(k, k) m(k, j) = m(k, j) * m(k, k),j = 0, 1, ..., n-1;j != k m(i, j) = m(i, j) - m(i, k) * m(k, j),i, j = 0, 1, ..., n-1;i, j != k m(i, k) = -m(i, k) * m(k, k),i = 0, 1, ..., n-1;i != k 最后,根據(jù)在全選主元過程中所記錄的行、列交換的信息進行恢復,恢復的原則如下:在全選主元過程中,先交換的行(列)后進行恢復;原來的行(列)交換用列(行)交換來恢復。
