求解线性方程组出现missing matlab operator

[gjrseason]

for m=0:1
for n=0:1
for o=0:1
for p=0:1
for q=0:1
w=[0 m m 0 0 0 0 0 0 0;0 -3 m 0 0 0 0 0 0 0;0 0 -2 0 0 0 0 0 0 0;0 0 0 0 n n 0 0 0 0;0 0 n 0 -3 0 0 n 0 0;0 0 0 0 0 -1 0 n 0 0;0 0 0 0 0 0 0 p 0 0;0 0 0 0 0 n+p 0 -5 0 0;0 0 0 0 0 0 0 0 -2 q;0 0 0 0 0 0 0 0 q -1];
v=[0 -m -m 4-o-p -o 0 2-o -2p-n -q 0]';
y=w\v
end
end
end
end
end

v矩阵有问题
??? v=[0 -m -m 4-o-p -o 0 2-o -2p-n -q 0]';

Error: Missing MATLAB operator.

请问是哪里有问题呢？谢谢 ……
