where y=M(t)/M(infinity), alpha(n) are roots of bessel function (first kind, zero order)
D and a are constants, D=5.46e-4, a=3
I'm trying to plot (t,y) for t=0:1:300 but not sure how to code for the roots of bessel function part. Any help is greatly appreciated, thank you!

The roots of the bessel function (first kind, zero order) can be obtained from the below code.
Z = 0:0.1:20;
J0 = besselj(0,Z);
alpha = roots(J0);
For more information, refer the following links.

I apologize for the above answer. However, the roots of the bessel function can be found using roots function from the given File Exchange link.
