erfcl - Linux


Overview

erfcl calculates the complementary error function. It is used to calculate the probability of an event that is outside of a certain range.

Syntax

erfcl <x>

Where:

  • <x> is the input value.

Options/Flags

None

Examples

# Calculate the complementary error function of 1.5
erfcl 1.5
0.006246049574356399

# Calculate the complementary error function of -3.2
erfcl -3.2
1.9999999999999992

Common Issues

  • If <x> is complex, erfcl will return a complex number.

Integration

erfcl can be used with other commands to calculate the probability of complex events. For example, the following command calculates the probability of an event that is between 1 and 3:

erfcl(1) - erfcl(3)
