I. 向量梯度 假设有一个映射函数为\(f:R^n→R^m\)和一个向量\(x=[x_1,...,x_n]^T∈R^n\),那么对应的函数值的向量为\(f(x)=[f_1(x),...,f_m(x)]^T∈R^m\). 现在考虑\(f\)对\(x_i\)的梯度为:\(\frac{\partial{f}}{\partial{x_i}}=[\frac{\partial{f_1}}{\partial{x_i}},...,\frac{\partial{f_m}}{\partial{x_i}}]^T∈R^…

Implement an iterator to flatten a 2d vector. For example,Given 2d vector = [ [1,2], [3], [4,5,6] ] By calling next repeatedly until hasNext returns false, the order of elements returned by next should be: [1,2,3,4,5,6]. Hint: How many variables do y…
