I am using the following code:
syms B1 B2 SWR Cv i = 1;Cv(1,2) = 0.39;B1(1,2) = 55;B2(1,2) = 29;while i<61 i = i + 1; Cv(i,2)= Cv(i-1) + 0.01; R = 0.5 == Cv(i,2)./2*(tan(B1*pi/180) + tan(B2*pi/180)); Cp = 0.5 == 1- (1+tan(B2*pi/180).^2)/(1+tan(B1*pi/180).^2); [B1(i,2),B2(i,2)] = vpasolve([R, Cp], [B1,B2]); SWR = Cv(i,2)*(tan(B1(i,2)*pi/180) - tan(B2(i,2)*pi/180)); X(i,2) = Cv(i,2); Y(i,2) = SWR;end
And it is giving me the following errors:
Warning: The system is inconsistent. Solution does notexist. > In symengine In sym/privBinaryOp (line 908) In / (line 309) In gasturbine_hw7_try2 (line 16) Error using sym.getEqnsVars>checkVariables (line 92)The second argument must be a vector of symbolicvariables.Error in sym.getEqnsVars (line 54) checkVariables(vars);Error in sym/vpasolve (line 132) [eqns,vars] = sym.getEqnsVars(varargin{1:N});Error in gasturbine_hw7_try2 (line 18) [B1(i,2),B2(i,2)] = vpasolve([R, Cp], [B1,B2]);
I am having trouble understanding why the errors are occurring. What I am trying to do is solve equation R and Cp for increasing values of Cv. So I am simply making an array for the variables B1, B2 and Cv and using the values in each index to solve for a specific value of SWR. I know you can do this using anonymous functions, but I am having trouble doing it that way and so am doing it this way. I seek help in this method, not the other.
