inner_product.m

最小二乘实现多项式拟合

function product = inner_product(vector1,vector2)
%计算行向量内积
%输入参数：做内积的两个行向量
%输出参数：向量的内积

product = 0;
m = size(vector1,2);
n = size(vector2,2);
if m==n
    for i = 1:m
        product = product + vector1(i) * vector2(i);
    end
else
    disp('错误！两个向量的维数不等！');
    return;
end
