clojure - Transform Incanter matrix to nested vector -


consider function outputs incanter matrix.

here example matrix containing output function:

a 6x4 matrix  -4.77e-01 8.45e-01  1.39e-01 -9.83e-18  8.55e-01 2.49e-01  1.33e-01  2.57e-17 -2.94e-03 6.60e-03 -9.63e-01  1.16e-16 ...  6.64e-09  2.55e-08  1.16e-07 -1.11e-16 -1.44e-01 -3.33e-01  1.32e-01 -7.07e-01 -1.44e-01 -3.33e-01  1.32e-01  7.07e-01

i'd continue analyzing rows of matrix, represent points. function want feed incanter matrix takes nested vectors inputs.

so function need above data in form

[[-4.77e-01 8.45e-01  1.39e-01 -9.83e-18]  [8.55e-01 2.49e-01  1.33e-01  2.57e-17]  [-2.94e-03 6.60e-03 -9.63e-01  1.16e-16]  [6.64e-09  2.55e-08  1.16e-07 -1.11e-16]  [-1.44e-01 -3.33e-01  1.32e-01 -7.07e-01] [-1.44e-01 -3.33e-01  1.32e-01  7.07e-01]]

it transformation incanter matrix representation nested vector structure unsure how perform. there simple way convert data's representation?

you can build-in to-vect function:

(to-vect m)

or build-in to-list function:

(to-list m)

both functions produce vector-of-vectors when given matrix:

=> (def m (matrix [[1 2] [3 4]]))  2x2 matrix  -------------  1.00e+00  2.00e+00   3.00e+00  4.00e+00   => (to-vect m) [[1.0 2.0] [3.0 4.0]] => (to-list m) [[1.0 2.0] [3.0 4.0]]
