% Computes the Gaussian form of the Legendre functions.
Will also compute the first derivatives, if requested.
Because there is no zero indexing in Matlab, the P's are offset
in the p matrix as follows:
n,m
p(n+1,m+1) = P
--------------------------------------------------------------------------
Form:
[p, dP] = PGauss( nMax, mMax, theta )
--------------------------------------------------------------------------
------
Inputs
------
nMax max value of first index
mMax max value of second index
theta input value (usually an angle in rads)
-------
Outputs
------- n,m
p Gauss functions, P
n,m
dP dP/d(theta)
