I am trying to create augmented matrix containing variables a and b, using the following code:
sage:
sage: u = Matrix([
....: [1, -1],
....: [2, 1]
....: ])
sage:
sage: var('a, b')
(a, b)
sage:
sage: w = vector([ a, b])
sage:
sage: u.augment(w, subdivide=True)
The last line, u.augment(w, subdivide=True), is giving me TypeError: unable to convert a to an integer.
