Hello,
I have to find the nonzero roots of an equation and then plug them into a summation. I determined chebfun is probably the best way to find the nonzero roots but I receive errors about the function being unresolved using 65000+ points and have I tried 'splitting on' which I think is due to tan(x) being in my function?
The function I need to non-zero roots for is below, where alpha is a previously found integer. I don't even need all the non-zero roots the first 5 or so (say a range of 0:30) would be sufficient): f = tan(x)-((3*x)./(3+alpha*(x^2)))
I then need to plug-in these non-zero positive roots to this second equation as the variable "r" so I was going to step through the roots matrix and sum the values of the function below. Again "alpha" is a pre-defined integer and so is "Deff". (6*alpha*(1+alpha)*exp(-Deff*(r.^2)*(t/(rS.^2))))/(9+9*(r.^2)*(alpha.^2))
Thank you! Melissa
