Right-tailed function of standard normal distribution, also known as (standard normal distribution) complementary cumulative distribution function
Error function
Complementary error function
relationship
Matlab itself has a Q function, namely qfunc ()
Its inverse function is
qfuncinv ()
y = qfuncinv (x)
Returns the parameter of the q function whose value of the q function is x. The input x must be an array of real numbers containing elements between 0 and 1.
The following example illustrates the inverse relationship between qfunc and qfuncinv.
x1 = [0 1 2; 3 4 5];
y1 = qfuncinv (qfunc (x1))
x2 = 0: .2: 1;
y2 = qfunc (qfuncinv (x2))
The output is as follows:
y1 = 0 1 2 3 4 5
y2 = 0 0.2000 0.4000 0.6000 0.8000 1.0000
