A decoding algorithm based on transform and fast hadamard transform changes the matrix multiplication to the addition , subtraction and position exchanging among the matrix elements , so reduces the demand of the instrument for computer 基于變換和快速阿達瑪變換的解碼算法,將矩陣乘法簡化為矩陣元素間的加、減運算和位置交換,降低了儀器對微機系統(tǒng)的要求。
At first , the dissertation analyses the discrete manufacture company ' s requirement to design change management and divides the requirement into two levels : the first one is assuring the product ' s data integrated , coincident , effectible and traceable ; the second one is correctly and punctually transforming change information 本文首先分析了離散產(chǎn)品制造企業(yè)對設(shè)計變更管理的需求,將需求劃分為兩個層次:保證產(chǎn)品數(shù)據(jù)的完整性、一致性、有效性和可跟蹤性;正確、及時地傳遞變更信息。
