I use yalmip for programming problem. the code is as follows:
f=sdpvar(3,3);
delta=[1 1 0
0 0 1
0 1 0
1 0 0
0 1 1];
for a=1:5
for i=1:3
x(a,i)=delta(a,:)*f(:,i);
end
end
t_0=[7,5
9.5,6
1,1
9,6
4,3];
gamma=[2, 1];
C=[400, 300, 450, 450, 100];
for a=1:5
for i=1:2
t(a,i)=t_0(a,i)*(1+0.15*((gamma(i)*x(a,i)/C(a))^4)); %error line
end
end
but the error is 'Unable to perform assignment because dot indexing is not supported for variables of this type'. Could you please help me find out the bug?

if i set the power less than 4 for the error row, it can just work. But larger than 4 will bring error.
