inverse

Convert authalic, conformal, isometric, or rectifying latitude to geodetic latitude

Syntax

phi = inverse(converter,lat)
phi = inverse(converter,lat,angleUnit)

Description

example

phi = inverse(converter,lat) returns the geodetic latitude coordinates corresponding to authalic, conformal, isometric, or rectifying latitude coordinates lat.

example

phi = inverse(converter,lat,angleUnit) specifies the units of output phi.

Input Arguments

collapse all

Latitude coordinates to convert, specified as a numeric scalar, vector, matrix, or N-D array.

The interpretation of lat depends on the latitude converter. If the conversion is:

  • authalic, lat represents the variable β (beta).

  • conformal, lat represents χ (chi).

  • isometric, lat represents ψ (psi). lat is a dimensionless number and does not have an angle unit.

  • rectifying, lat represents μ (mu).

For authalic, conformal, and rectifying conversions, the values of lat must be consistent with angleUnit.

Units of latitude coordinates, specified as 'degrees' or 'radians'.

Output Arguments

collapse all

Geodetic latitude coordinates, specified as a numeric scalar value, vector, matrix, or N-D array. phi is the same size as lat. If angleUnit is not supplied, phi is in degrees. Otherwise, values of phi are consistent with the units of angleUnit.
