(Matlab) How to get inverse function?

[davyzhu]

matlab inverse function

Hi all,

The function may be too complex to get inverse function, like y=x*2^x*log2(x).

I used to use C do inverse function.
The procedure is:
(1) get x->y pair matrix
(2) qsort, i.e quick sort y
(3) bsearch to get x

Is there any good method to get inverse function in Matlab?

Best regards,
Davy
