PlBar
Compute all the 4-pi (geodesy) normalized Legendre polynomials.
Usage
call PlBar (p
, lmax
, z
, exitstatus
)
Parameters
p
: output, real/*8, dimension (lmax
+1)- An array of geodesy-normalized Legendre polynomials up to degree
lmax
. Degreel
corresponds to array indexl+1
. lmax
: input, integer- The maximum degree of the Legendre polynomials to be computed.
z
: input, real/*8- The argument of the Legendre polynomial.
exitstatus
: output, optional, integer- If present, instead of executing a STOP when an error is encountered, the variable exitstatus will be returned describing the error. 0 = No errors; 1 = Improper dimensions of input array; 2 = Improper bounds for input variable; 3 = Error allocating memory; 4 = File IO error.
Description
PlBar
will calculate all of the 4-pi (geodesy) normalized Legendre polynomials up to degree lmax
for a given argument. These are calculated using a standard three-term recursion formula. The integral of the geodesy-normalized Legendre polynomials over the interval [-1, 1] is 2.
