第一种思路——把向量的各个维度放到数组里: #include<stdio.h>#include<stdlib.h>intnorm(intbases[],intlength){intsum=0;for(inti=0;i<length;i++){sum+=1-bases[i]%2;}returnsum;}intnextVector(intbases[],intlength){intcarry=1;for(inti=length-1;i>=0;i--){bases[i]+=carry;carry=0...
if ( ( flag >= -NORM ) && ( flag <= NORM ) ) { A; } 注意:应特别注意在 int、指针型变量和“零值”比较的时候,把“零值”放在左边,这样当把“==” 误写成“=”时,编译器可以报错,否则这种逻辑错误不容易发现,并且可能导致很严重的后果。面试题 3:sizeof 和 strlen 的区别 ...

The user can read .fil files or provide a std::vector<unsigned short> or a raw pointer of type unsigned short, but must in either case provide a valid aa_filterbank_metadata object that matches a filterbank data file (sigproc format)....
当使用3d图形时,示例着色器通常使用以下操作进行矢量位置转换: result = mul(matrix, vector); 这显然意味着: result = mul(vector, matrix_transposed); 另外,为了简单起见,大多数线性代数库宁愿只保留vector * matrix乘法操作。 Now:假设我想转换一些vector (例如,位置),使用一些具体的矩阵(具体的,让我们使用D3DX...
