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.

反函数就是符号求解原来的函数就可以了。
