: psi = geo2iso (phi)

: psi = geo2iso (phi, spheroid)

: psi = geo2iso (phi, spheroid, angleUnit)

Return the isometric latitude given geodetic latitude phi.

Input

• phi: the geodetic latitude. Can be a scalar value, a vector or an ND-array.

• (optional) spheroid: referenceEllipsoid. For admissible values see ‘referenceEllipsoid.m‘. The default ellipsoid is WGS84. is wgs84.
• (optional) angleUnit: string for angular units (’degrees’ or ’radians’, case-insensitive, just the first character will do). Default is ’degrees’.

Output

• psi: the isometric latitude(s), same shape as phi.

Example

geo2iso (45)
ans =  50.227
