Vector to Scalar

Hi there,

I am using this following code to get this weighted average heat capacity value. When I use this value in another file as a divisor there is an "mldivide" error suggesting that this value is either a vector or matrix. Can someone help me as to where am I making the mistake and what. The independent variables like "T0" and "R" have been defined beforehand and have a constant value. Size check of Cpg1 results in... 1 1 ... . Thanks in advance.

% ------ Calculation of Sp. Heat Capacity of Gas Mixture "Cpg" ------

Cp1=(4.568-8.975e-3*T0+3.631e-5*T0^2-3.407e-8*T0^3+1.091e-11*T0^4)*R; % J/mol.K Cp2=(3.259+1.356e-3*T0+1.502e-5*T0^2-2.374e-8*T0^3+1.056e-11*T0^4)*R; % J/mol.K Cp3=(3.912-3.913e-3*T0+1.182e-5*T0^2-1.302e-8*T0^3+0.515e-11*T0^4)*R; % J/mol.K Cp4=(4.395-4.186e-3*T0+1.405e-5*T0^2-1.564e-8*T0^3+0.632e-11*T0^4)*R; % J/mol.K Cp5=(2.883+3.681e-3*T0-0.772e-5*T0^2+0.692e-8*T0^3-0.213e-11*T0^4)*R; % J/mol.K Cp6=(3.539-0.261e-3*T0+0.007e-5*T0^2+0.157e-8*T0^3-0.099e-11*T0^4)*R; % J/mol.K % Cp=[Cp1 Cp2 Cp3 Cp4 Cp5 Cp6]; % Cpg1=sum(y.*Cp); % J/mol.K Cpg1=y1*Cp1+y2*Cp2+y3*Cp3+y4*Cp4+y5*Cp5+y6*Cp6; Cpg=Cpg1/(Mm*1e-3); % J/kg.K % size(Cp1);
