Computes the Legendre elliptic integral of the second kind. You must manually select the polymorphic instance you want to use.

Details  

Use the pull-down menu to select an instance of this VI.

Complete Elliptic Integral E

k is the modulus argument. k is a real number between 0 and 1.
E(k) is the value of the complete elliptic integral of the second kind.

Incomplete Elliptic Integral E

k is the modulus argument. k is a real number between 0 and 1.
a is the amplitude of the function, which is the upper limit of the integral. The default value is /2.
E(k, a) is the value of the incomplete elliptic integral of the second kind.

Elliptic Integral of the 2nd kind Details

Complete Elliptic Integral E

The following equation defines the complete elliptic integral of the second kind.

where k is the modulus.

Incomplete Elliptic Integral E

The following equation defines the incomplete elliptic integral of the second kind.

where k is the modulus and a is the upper limit, or amplitude, of the integral.

The following intervals for the input values define the function.

LabVIEW supports the entire domain of this function that produces real-valued results. For any real value of upper limit a, the function is defined for all real values of k in the unit interval.
