How to solve two differential equations in MATLAB and plot it?

I have two differential equations: da/dt=a(0.3*a^(−3)+.7)^(1/2) and dτ/dt=1/a. The initial conditions are t=0; a=1 and τ=0, respectively (say).
How can I solve the equations in MATLAB? I need to plot 'a' vs 'τ' from this solution.
Thanks in advance.
