help

Gives helpful information on the usage and purpose of a function. Ex:

help('LU')
would print out:
Usage: LU(<matrix>) Computes an LU factorization of a general M-by-N
matrix using partial pivoting with row interchanges. Factorization has
the form A = P*L*U.On exit, the input matrix is comprised of the
factors L and U from the factorization A = P*L*U.
Returns an integer vector. The row i of A was interchanged with row IPIV(i).  
Ex: LU([1,2;3,4]) 
See: http://www.osl.iu.edu/research/mtl/doc/getrfLapackMatrixVectorInt.html

The ``Usage'' line shows how to invoke the function and the sort of arguments it can take. In this case, the LU function takes one argument, and it must be a matrix.
