美化Matlab的输出又名人类可读形式的输出? [英] Beautifying the output of Matlab aka human-readable form for output?

问题描述

syms x y z;
solve(x==y+1, y^2==z,z==9) 

ans = 

x: [2x1 sym] 
y: [2x1 sym] 
z: [2x1 sym]

，现在我想看到类似Mathematica为Solve[{x == y + 1, y^2 == z, z == 9}, {x, y, z}]输出{{x->-2,y->-3,z->9},{x->4,y->3,z->9}}的结果.工作区窗口，然后是变量编辑器，向我显示了此，但我仍然看不到存储的实际值在那里.

and now I want to see the results like Mathematica outputting {{x->-2,y->-3,z->9},{x->4,y->3,z->9}} for Solve[{x == y + 1, y^2 == z, z == 9}, {x, y, z}]. The workspace window and then variable editor shows me this but I still cannot see the real values stored there.

如何以易于理解的形式(又称为美化形式)查看Matlab的输出?

推荐答案

solve 状态:

求解方程组时，使用一个输出参数以结构数组的形式返回解决方案

When solving a system of equations, use one output argument to return the solutions in the form of a structure array

结果作为结构返回，因此您可以访问每个字段以查看其值.该文档提供了如何执行此操作的示例:

The result is returned as a struct, so you can access each field to see its value. The documentation brings an example of how to do it:

S = solve(x==y+1, y^2==z, z==9);
[S.x, S.y, S.z]

这应该导致:

ans =
     4     3     9
    -2    -3     9

或者，您可以通过指定多个输出参数以单独的变量返回解决方案:

Alternatively, you can return the solutions in separate variables by specifying multiple output arguments:

[solx, soly, solz] = solve(x==y+1, y^2==z, z==9)

这将导致:

solx =
     4
    -2

soly =
     3
    -3

solz =
     9
    -9
