[B,A] = FindLinMod(X,n_dimension)

Find an n_dimension linear model for the
data in the columns of X.

B - basis matrix for the linear model
(n_wavelengths by n_dimension)
A - coefficients to approximate data within model
(n_dimension by n_data)
X - matrix whose columns contain the data
(n_wavelengths by n_data)
(n_data >= n_dimension)
n_dimension - dimension of the linear model to find
