all of the variables n, st, st2, st3, st4, st5, st6, sx, sxt, sxt2, and
sxt3 are all floats.

A = array([[N, st, st2, st3],[st, st2, st3, st4], [st2, st3, st4, st5],
[st3, st4, st5, st6]])
B = array    ([sx, sxt, sxt2, sxt3])
lina = linalg.solve(A, B)

is there something wrong with this code?

it is returning

  File "C:\PYTHON23\Lib\site-packages\numpy\linalg\linalg.py", line 138,
in solve
    raise LinAlgError, 'Singular matrix'
numpy.linalg.linalg.LinAlgError: Singular matrix

Does anyone know what I am doing wrong?
