Return geocentric latitude (psi) given geodetic latitude (phi) and flattening.
The default input and output is in degrees; use optional third parameter angleUnit for radians. phi can be a scalar, vector, matrix or any ND array. flattening must be a scalar value in the interval [0..1).
Examples Scalar input:
psi = geocentricLatitude (45, 0.0033528) => psi = 44.8076
Also can use radians:
psi = geocentricLatitude (pi/4, 0.0033528, "radians") => psi = 0.78204
Vector Input:
phi = 35:5:45; psi = geocentricLatitude (phi, 0.0033528) => psi = 34.819 39.811 44.808
