Complete elliptic integral of the first kind
MuPAD® notebooks will be removed in a future release. Use MATLAB® live scripts instead.
MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.
ellipticK(m) represents the complete elliptic
integral of the first kind which
is defined as
The complete elliptic integral of the first kind is defined for a complex argument m.
For floating-point values
floating-point results. For most exact arguments, it returns unevaluated
symbolic calls. You can approximate such results with floating-point
numbers using the
When called with floating-point arguments, this function is
sensitive to the environment variable
DIGITS which determines
the numerical working precision.
Most calls with exact arguments return themselves unevaluated.
To approximate such values with floating-point numbers, use
Alternatively, use a floating-point value as an argument:
ellipticK(0) has a special value:
An arithmetical expression specifying the parameter.
