parametricLatitude

Convert geodetic to parametric latitude

Syntax

beta = parametricLatitude(phi,F)

beta = parametricLatitude(phi,F,angleUnit)

Description

beta = parametricLatitude(phi,F) returns the parametric latitude corresponding to geodetic latitude phi on an ellipsoid with flattening F.

beta = parametricLatitude(phi,F,angleUnit) specifies the units of input phi and output beta.

Examples

Convert Geodetic Latitude to Parametric Latitude

Create a reference ellipsoid and then convert the geodetic latitude to parametric latitude. The reference ellipsoid contains a flattening factor.

s = wgs84Ellipsoid;

parametricLatitude(45, s.Flattening)

ans =

   44.9038

Convert Geodetic Latitude Expressed in Radians to Parametric Latitude

Create a reference ellipsoid and then convert a parametric latitude expressed in radians to geodetic latitude. The reference ellipsoid contains a flattening factor.

s = wgs84Ellipsoid;

parametricLatitude(pi/3, s.Flattening, 'radians')

ans =

    1.0457

Input Arguments

phi — Geodetic latitude of one or more points

scalar value, vector, matrix, or N-D array

Geodetic latitude of one or more points, specified as a scalar value, vector, matrix, or N-D array. Values must be in units that match the input argument angleUnit, if supplied, and in degrees, otherwise.

Data Types: single | double

F — Flattening of reference spheroid

scalar

Flattening of reference spheroid, specified as a scalar value.

Data Types: single | double

angleUnit — Unit of measurement for angle

'degrees' (default) | 'radians'

Unit of measurement for angle, specified as 'degrees' or 'radians'.

Data Types: char | string

Output Arguments

beta — Parametric latitudes of one or more points

scalar value, vector, matrix, or N-D array

Parametric latitudes of one or more points, returned as a scalar value, vector, matrix, or N-D array. Values are in units that match the input argument angleUnit, if supplied, and in degrees, otherwise.
