我正在尝试解决具有自由度的符号系统.它假设使用参数,但它无法处理一些简单的事情,例如:
I'm trying to solve a symbolic system with degrees of freedom. It supposes to use parameters, but it fails to handle something simple such as:
syms x1 x2 x3 x4 x5 x6 x7 x8 real con = [ x1 + x2 + x3 + x4 + x5 + x6 + x7 + x8 == 1080 x2 + x3 == 0 x6 + x7 == 0 ]; s = solve(con, 'ReturnConditions', 1 ,'PrincipalValue', true)输出:
Warning: Unable to find explicit solution. For options, see help. > In solve (line 317) In testm (line 10) In run (line 91) s = struct with fields: x1: [0×1 sym] x2: [0×1 sym] x3: [0×1 sym] parameters: [1×0 sym] conditions: [0×1 sym]Lucien 的解决方案也适用于此:
Lucien's solution applies to this as well:
求解具有整数变量的符号方程
推荐答案也许可以帮到你.
s = solve(con, [x1 x2 x3 x4 x5 x6 x7 x8], 'ReturnConditions', 1 ,'PrincipalValue', true);
