| Solve a linear system m.x=b with WL-Function Minimize: In[1]:= m = {{10, 7, 5}, {9, 7, 4}, {1, 4, 10}}; b = {3, 5, 3}; Minimize[{Norm[\!\(\* TagBox["m", Function[BoxForm`e$, MatrixForm[BoxForm`e$]]]\) . {x1, x2,... |
| Definition of a boundary value problem: pde = {-(1050000/13) D[u[x, y, z], z, z] - 1050000/13 D[u[x, y, z], y, y] - 2625000/13 D[w[x, y, z], x, z] - 2625000/13 D[ v[x, y, z], x, y] - 3675000/13 D[u[x, y, z], x, x]... |
| Thank you very much for the answer, but what does this mean in this code example: pde = {-(1050000/13) D[u[x, y, z], z, z] - 1050000/13 D[u[x, y, z], y, y] - 2625000/13 D[w[x, y, z], x, z] - 2625000/13 D[ v[x, y, z], x, y]... |
