error in solving system of nonlinear equations

I am trying to solve four nonlinear equation simultaneously on matlab. But I am getitng the "Comma separated list expansion has cell syntax for an array that is not a cell".

The screenshot of error is attached.

My code is given below.

syms x y z T
x1=1;
x2=1;
x3=1;
x4=1;
y1=1;
y2=1;
y3=1;
y4=1;
z1=1;
z2=1;
z3=1;
z4=1;
c=1;
t1=1;
t21=1;
t31=1;
t41=1;
eq1 = ((x1 - x)^2 + (y1 - y)^2 + (z1 - z)^2 )^1/2 - (c * t1) + (c * T)==0;
eq2 = ((x2 - x)^2 + (y2 - y)^2 + (z2 - z)^2 )^1/2 - (c * t21) - (c*t1) + (c*T)==0;
eq3 = ((x3 - x)^2 + (y3 - y)^2 + (z3 - z)^2 )^1/2 - (c * t31) - (c*t1) + (c*T)==0;
eq4 = ((x4 - x)^2 + (y4 - y)^2 + (z4 - z)^2 )^1/2 - (c * t41) - (c*t1) + (c*T)==0;
sol = solve(eq1, eq2, eq3, eq4);
xSol = sol.x
ySol = sol.y
zSol = sol.z
TSol = sol.T

What release are you using? When I run this code I don't get this error.

Did you notice the warning above the error? There is no explicit solution, so when you try to extract it that doesn't really make sense.

I am using R2014a release.

Kindly guide what should I do

Answer 1

[madhan ravi]

sol = solve([eq1, eq2, eq3, eq4],[x,y,z,T]); %proper way to use solve

[madhan ravi]

Why not use fsolve(...)?

[Muhammad Ali]

getting the same error using the command you gave for solve function.

Kinldy guide how can I use fsolve in this code

Are you sure there should be an explicit solution? What would you expect your output to be if you wanted to solve sin(x)==2?
