根据此数据,构造的公式及其矩阵形式为 要解此方程需要利用最小二乘方法。 2. 最小二乘方法 对于上例所示的系统,A为m*n且m>n的矩阵,被成为超定的(overdetermined)。一般,它没有解。例如,当m=3,n=2时,A的两个列向量和在空间图形如下,我们希望能获得此列向量的线性组合以使。从图中,可清楚看出这是不可能...
对于上例所示的系统 ,A为m*n且m>n的矩阵,被成为超定的(overdetermined)。一般,它没有解。例如,当m=3,n=2时,A的两个列向量 和 在 空间图形如下,我们希望能获得此列向量的线性组合以使 。从图中,可清楚看出这是不可能的,因为b并不在 和 张成的空间中。 这时,因为无法求求解,退而求其次,我们希望解x1...
The matrix least squares (LS) problem minX |AXB T T|F is trivial and its solution can be simply formulated in terms of the generalized inverse of A and B. Its generalized problem minX 1,X 2|A 1X 1B 1T + A 2X 2B 2T T|F can also be regarded as the constrained LS problem minX...
