I have an empty matrix that name q_bar, then I will add q_bar with matrix (b_bar.mul(evec)). Evec matrix has 5 row and 5 column.
Then the system said that "no operator "+" matches these operands.
Mat rata, Qnew, yminq,q_bar, evec,etrans,b_bar, q_new,qbaru, input, y_bar;
FileStorage smp0("mall.txt", cv::FileStorage::READ);
FileStorage smp1("evecall.txt", cv::FileStorage::READ);
FileStorage smp2("a0.txt", cv::FileStorage::READ);
ab[0] = smp0["Point"];
ab[1] = smp1["Point"];
ab[2] = smp2["Point"];
read(ab[0],pointz);
read(ab[1],evec);
read(ab[2],jnt[0]);
t2=t;
t.clear();
etrans = evec.t();
Qnew = Mat (t2).reshape(0,5);
yminq = Qnew - q_bar;
b_bar = etrans.mul(yminq);
q_new = q_bar + (b_bar.mul(evec));
I dont know why, this source code suddenly error when I move to other project.
Then I try to use add function, the system get error. this is the error
