Matrix Dimensions Must Agree Error, Error using +
-2*(D2*(q_(1,:)'))-2*pr.*(f_(1,:)').*(D1*(q_(1,:)'))... +2*pr.*A*(D1*(f_(1,:)')).*((q_(1,:)'))-de.*pr.*((A*(f_(1,:)'))....

Matrix dimensions must agree.
i can get graph if i give one value to pr ,but when i give more than one value it give me this error.
