Solves the list of simultaneous linear equations for the list of variables.
The first list represents the equations to be solved; the second list is a list of the unknowns to be determined.
If the total number of variables in the equations is equal to the number of equations, the second argument-list may be omitted.

The primitive equations are a version of the Navier-Stokes equations which describe hydrodynamical flow on the sphere under the assumptions that vertical motion is much smaller than horizontal motion (hydrostasis) and that the fluid layer depth is small compared to the radius of the sphere.
Einstein's famous equations says that mass m is equivalent to energy E, and the amount of energy contained in a piece of mass is equal to the mass multiplied with the square of the speed of light, c.

Equations (4-1) through (4-7) are used to calculate the linearized continuum magnitude at each of the HB filter wavelengths.
Absolute fluxes are obtained using: equations (5-1) through (5-4) for the continuum filter measurements, equations (6-1) through (6-7) for the interpolated continuum under the gas species, and equations (7-1) through (7-7) for the measurements with the gas filters themselves.
The required list indicates that a measurement in at least one of the listed filters is necessary for proper continuum determination.

The instrument list may be different for each equation (see the MASK option or the INST option) and the form of the covariance matrix used for weighting the estimator is under user control (the HETERO option for heteroskedastic-consistency and the NMA= option for moving average disturbances).
List the instruments in the INST= option and list the equations after the options; the products of these two are the orthogonality conditions, which are minimized in the metric of an estimate of their expected covariance.
The matrix is # of instruments by # of equations and the default is a matrix of ones (all instruments used for all equations).

In equation 1 the variables y and x are raised to the first power (1), while in equation 7 x is raised to the second power (2).
Equation 3, meanwhile, does satisfy our condition for a linear relationship, the only difference is that y depends on two exogenous variables, x and z.
In the linear equation, if we are at x = 1 and z = 2 and move to x = 2, then y increases by 4.

 FC++ lazy list implementation   (Site not responding. Last check: 2007-10-13)
As of v1.3, lists have been completely reimplemented in a way that is far more efficient than the previous implementation.
This document describes the new list implementation structure, and how you can write functoids to take advantage of the new structure to be more efficient.
However, the "odd" lists described in that paper always evaluate "one too far ahead" in a list, whereas FC++'s OddLists effectively have "even" tails, which means only the original call is too eager; the recursive calls are fine.
