The file test.input contains the following:
cat test.input
FF ==> PF 109
VF ==> Vector FF
)expose VectorSpaceBasis
V : VF := [39, 29]
W : VF := [18, 5]
isBasis?([V, W])
M : Matrix FF := [V, W]
rank M
Here's the test run:
(1) -> )r test
FF ==> PF 109
VF ==> Vector FF
)expose VectorSpaceBasis
VectorSpaceBasis is now explicitly exposed in frame frame1
V : VF := [39, 29]
(3) [39, 29]
W : VF := [18, 5]
(4) [18, 5]
isBasis?([V, W])
(5) true
M : Matrix FF := [V, W]
┌39 29┐
(6) │ │
└18 5 ┘
rank M
(7) 1
(8) ->
Vectors V and W are linearly dependent but isBasis returns "true".
Thanks,
