I get this message, if I run your code:
Undefined function or variable 'Pr'.
Error in
odeequation>@(x,y)[y(2);y(3);((-(y(1)*y(3))+M*(y(2)-1)+y(2)^2-Gr*y(4)-Gc*y(6))/(1+1/beta));y(5);(-Pr*(y(1)*y(5))-Pr*Ec*(1+beta^-1)*y(3)^2-Pr*Ec*(y(2)-1)^2*M)/(1+(4/3)*R);y(7);-Sc*(y(1)*y(7))-Sc*K*y(6)]
Error in bvparguments (line 105)
testODE = ode(x1,y1,odeExtras{:});
Error in bvp4c (line 130)
bvparguments(solver_name,ode,bc,solinit,options,varargin);
Error in odeequation (line 12)
fsol = bvp4c(dydx,res,solinit);
This looks, like the problem is inside the function "Pr". Please look there or post this function.

The boundary conditions contain the final time infinity. Of course you cannot integrate to infinity, because this would need an infinite amount of time. But a boundary at infinity is only meaningful, if the values are constant there. This means, that all derivatives must vanish at this point.
Can you transform the equations mathematically such, that knowing the values and vanishing derivatives at t=Inf allows to determine the corresponding missing initial conditions? Then you would get an initial value problem, which can be solved by an integrator instead of a BVP solver.
