HELLO EVERYBODY
MY QUERY IS QUIET SIMPLE.CAN ANYBODY PLZZZZ HELP ME OUT
i run the following code on matlab
x_p = 4; y_p = 5; z_p = 2;
x_1 = 8; y_1 = 9; z_1 = 5;
x_2 = 2; y_2 = 5; z_2 = 1;
x_3 = 6; y_3 = 1; z_3 = 3;
c=3.0*10^8;
t1 = 5.692820*10^-9;
t2 = -2.924173*10^-9;
t3 = -12.010097*10^-9;
syms xs ys zs %our unknowns
eqn1 = sqrt((xs-x_p)^2+(ys-y_p)^2+(zs-z_p)^2)-sqrt((xs-x_1)^2+(ys-y_1)^2+(zs-z_2)^2)-(c*t1);
eqn2 = sqrt((xs-x_p)^2+(ys-y_p)^2+(zs-z_p)^2)-sqrt((xs-x_2)^2+(ys-y_2)^2+(zs-z_2)^2)-(c*t2);
eqn3 = sqrt((xs-x_p)^2+(ys-y_p)^2+(zs-z_p)^2)-sqrt((xs-x_3)^2+(ys-y_3)^2+(zs-z_3)^2)-(c*t3);
sol = solve([eqn1, eqn2, eqn3], [xs ys zs]);
m = 1;
for n = 1:length(sol.xs)
possibleSol(1,m) = double(sol.xs(n));
possibleSol(2,m) = double(sol.ys(n));
possibleSol(3,m) = double(sol.zs(n));
m= m+1;
end
AND THIS IS THE OUTPUT I GOT
I AM GETTING two possible solutions for x,y,z.i want to use if else loop to filter my result and i want to ignore the whole entry where a negative or complex value is present.
e.g
this is what i think code should be
ind=1
for n=1:colNo
if (1,n<0)or(2,n<0)or(3,n<0)
else validSol=possibleSol(:,n)
ind=ind+1;
end
but it has error so i want to have a loop maybe which only give the required entry which is non negative and non complex
