Question
请问用solve函数求方程出不来解，是不是得用fslove函数！。
Tr_t=T_i*(Pr_t/P_i).^((r-1)/r); %求解质量流量 m_t=-m_i/r./Pr_t.*(Pr_t/P_i).^(1/r).*dPr_t; syms Mu_t; f=Pu_t*((r/R)^0.5)*A*Mu...

加入先验知识为什么能缩小解空间的范围。
对于目标函数中含有欠定问题的，可能方程个数远小于未知数的个数，有很多解，导致不能确定唯一解，这种情况下，看论文经常有加入先验知识比如先验图像进行约束的，说可以缩小解空间的范围，为什么呢，加入先验知识并没有改变维数啊 怎么缩小解空间范围了？
