    Find the semiminor axis length of an ellipse from the eccentricity and length of the semimajor axis.

    b = minaxis(6378137,0.0818)
    b = 6.3568e+06

    Input Arguments

    collapse all

    Semimajor axis length, specified as a numeric scalar.

    Eccentricity of the ellipse, specified as a numeric scalar. The value of ecc must be in the range [0, 1].

    Data Types: single | double

    Output Arguments

    collapse all

    Semiminor axis length, returned as a numeric scalar. The units of b are the same as those of semimajor.
