现在要求解这样一个问题:规定newHash的前两位以00开头,求input的string可以是什么。注意我们只规定了newHash的头两位,而不是所有位数,满足这样要求的input可能有很多,但是仍然因为即使已知output,反向求input很困难,所以只能用暴力穷举法,比如把’hello MATLAB’和整数做strcat,然后计算DataHash,如果不符合要求,就试下一...

1.如何有效的初始化结构体数组(array of struct)? 例如: a = [] for i = 1:100 a(i).x = i; end 1. 2. 3. 4. 答: 使用repmat是预分配结构体最高效的方式。 N = 10000; b = repmat(struct('x',1), N, 1 ); 1. 2. 在Matlab2011b上进行了测试,其速度比使用索引的方式预分配内存块...
