Nullspace，指的是由“零元素”构成的空间，通常指某个“向量空间”的“零子空间”。例如，在由全部两行三列实矩阵组成的“向量空间”里，nullspace就是一个元素构成的子空间，具体形式如：┌ 0 0 0┐ └0 0 0┘ 值得注意的是，nullspace与特征向量的概念并无直接关联。在矩阵理论中，特征向量是...

I can't get the null space of a Matrix. This is how the matrix is calculated (use values Ta_in=3000, k_in=3, inputnumber=1 as reference): 테마복사 function Mat = Matrix(Ta_in,k_in,inputnumber) syms zeta(x) Psi(x) V(x) ypsilon0(x) sigma k Ta ypsilon0 Dypsilon0 ...
This part can't give me the nullspace of matrix t after reduced for some reasons (I recently did some research on the Internet and see some people said about the bug of **rref** and **null**). The problem is that it keeps showing me elementary matrix ...
