- Results of computations may be overwritten in-place on the input
arguments, in many cases without any memory or computational overhead.
For instance, the Cholesky factorisation of a positive-definite
symmetric matrix is a lower triangular matrix factor. In Gandalf
the operation can be performed in-place on the symmetric matrix
input argument, producing a lower triangular matrix.
See the function
`gan_squmat_cholesky_i()`. - The same structure can be used to store the results of several
computations, whether or not the sizes and types of the output
results vary. This saves many calls to
`malloc()`and`free()`.
