hi
this is the file from which i am reading the data
12,'z','x','o','p','q','r','s','t','u','v','w','T','A*p+B*u','y*p+D*q+E*r+F*s','G*q+H*r+I*t','J*q+K*s+L*x','M*r+N*o+O*t+2*x*P','2*x*Q+R*o+S1*s+P*t+U*T+V*z','W*o+N*t+X*T+R*2*x+Y*v','d*w+e*v+f*u','g*u+h*p+i*w+j*v','k*v+l*o+m*w+n*u','Z*T+2*x*a+b*z+c*o'

using
fid=fopen('/sim/TLV1117LV_DS/x0138322/scripts/userinput.m');
while(1)
tline1 =fgetl(fid);

%if (tline1 == -1), break, end
if isempty(tline1), break, end

TL1 =sym(tline1);
end
eq1=TL1(14);
eq2=TL1(15);
eq3=TL1(16);
eq4=TL1(17);
eq5=TL1(18);
eq6=TL1(19);
eq7=TL1(20);
eq8=TL1(21);
eq9=TL1(22);
eq10=TL1(23);
eq11=TL1(24);S=solve(eq1,eq2,eq3,eq4,eq5,eq6,eq7,eq8,eq9,eq10,eq11,TL1(3),TL1(4),TL1(5),TL1(6),TL1(7),TL1(8),TL1(9),TL1(10),TL1(11),TL1(12),TL1(13));
it run succesfully but i want the value of each varible
for which i did
S.TL1(8)
which gives error as
??? Access to an object's fields is only permitted within its methods.

Please tell me a way to get value of each varible from solve

Thank you in advance

You didn't get a reply in 36 minutes and are throwing a tantrum? I'm sorry, but I don't think that makes you a top priority for other newsreaders.

Instead of writing a file that you then need to read using FOPEN, FGETL,
etc. why not simply write a script file you can _execute_ to define your
expressions? The contents would be something like:


syms z x o p q r s t u v w T
eq = cell(1, 11);
eq{1} = someSymbolicExpression1;
eq{2} = someSymbolicExpression2;
% etc.

variablesToSolveFor = {z, x, o, p, q, r, s, t, u, v, w}
solution = solve(eq{:}, variablesToSolveFor{:});


To extract a particular variable, convert the symbolic variable from
variablesToSolveFor into the char array containing its name using the CHAR
method, then use dynamic field names.

solution.(char(variablesToSolveFor{4})) % Returns solution.p
