matlab里如何表示一个函数的反函数,如表示Q函数的反函数?
在matlab:
function [y]=Qfunc(x)
[y]=1/2*erfc(x/sqrt(2))
那如何表示Qfunc的反函数?

FINV Inverse of the F cumulative distribution function.
X=FINV(P,V1,V2) returns the inverse of the F distribution
function with V1 and V2 degrees of freedom, at the values in P.
The size of X is the common size of the input arguments. A scalar input
functions as a constant matrix of the same size as the other inputs.
