@(@\newcommand{\B}[1]{ {\bf #1} } \newcommand{\R}[1]{ {\rm #1} }@)@ Convert a cppad_py Vector to a Numpy Array
Syntax
array = cppad_py.utility.vec2numpy(vec, nr)
array = cppad_py.utility.vec2numpy(vec, nr, nc)

vec
This must have one of the following types: cppad_py.vec_int, cppad_py.vec_double, vec_py.vec_a_double. with size equal to nr*nc .

nr
This is an int equal to the number of rows in the array. If the argument nc is not present, the array is a vector; i.e., len( array.shape ) == 1 .

nc
If this argument is present, it is an int equal to the number of columns in the array. In this case the array is a matrix; i.e., len( array.shape ) == 2 .

array
This is the array corresponding to vec in row major order. Note that this array can be used after the vector vec drops out of scope (is deleted).
