Calculates the inverse complementary error function as defined by the following equation in relationship to the inverse error function erfinv:

 

 

Supported Product: FDTD, MODE, DEVICE, INTERCONNECT

 

Syntax

Description

out=erfcinv(z);

Returns the inverse complementary error function of z where z is a scalar number or matrix of scalar numbers.

 

For inputs outside the interval (0, 2), erfcinv returns NaN.

 

Example

Plot the inverse complementary error function for 0<z<2.

z=0.01:0.05:1.99; 

erfcinv_z = erfcinv(z);

plot(z,erfcinv_z,"z","erf");

 

The following figure shows the plot created by the example code.
