erfc_inv (MathScript RT Module Function)
Owning Class: advanced
Requires: MathScript RT Module
Syntax
y = erfc_inv(x)
Legacy Name: erfcinv
Description
Computes the inverse of the complementary error function associated with a normal distribution. y = erfc_inv(x) is equivalent to x = erfc(y).
Inputs
| Name | Description |
|---|---|
| x | Specifies complementary error function values. x is a matrix with elements in the interval [0, 2]. |
Outputs
| Name | Description |
|---|---|
| y | Returns the value of the inverse complementary error function of x. |
Examples
% Compute the inverse complementary error function at 1.386:
Y = erfc_inv(1.386)
% Plot the inverse complementary error function:
X = 0:0.01:1.9;
Y = erfc_inv(X);
