Maple 不解方程
我正在尝试求解这些方程:
S :=solve({ PVA1+PSA1+PPA1=1, PVA2+PSA2+PPA2=1, PVA3+PSA3+PPA3=1, PVA1*0.2+PVA2*0.5+PVA3*0.3= 0.3, PSA1*0.2+PSA2*0.5+PSA3*0.3=0.2, PPA1*0.2+PPA2*0.5+PPA3*0.3=0.3}, 显式=true);
但枫树给出了 S := NULL。有什么想法吗? PS 方程有一些解。

But maple gives S := NULL. Any ideas? PS equations have some solutions.

您发布的线性系统不一致。您可以通过编写以下内容来亲自检查:
要确切了解不一致的原因,请查看以下结果的最后一行
The linear system as you have posted it is inconsistent. You can check this out for yourself by writing:
To see exactly why it is inconsistent look at the last row resulting from
