zeros(1,y) % 返回一个1行y列的向量，数值全为0。x1=[x1 zeros(1,N-length(x1))]; %在x1向量后面补充0，使其长度变为N 。

这里的n是前面定义好的一个数组或矩阵,length(n)是求它的长度.前两句是定义一个和n一样长的一维数组或矩阵.这里面的n1和n2都是已知的数组.find((n>=min(n1))&(n=min(n1))&(n 结果一 题目 matlab中一小段序列相加相乘的理解问题 x1=zeros(1,length(n))x2=zeros(1,length(n))x1([find((n>=...

In other words, to solve the original moment conditional for the IVQR model, we need to find a α(τ ) such that the auxiliary quantile regression of y − dα(τ ) on x and z produces zeros for the coefficients on the instruments z. In practice, we want γ(τ ) as close to 0...
