  The Landauer-B\"uttiker conductivity of arbitrary uniaxial spatially
dependent strain in an armchair graphene nanoribbon is studied. Due to the
uniaxial character of the strain, the corresponding transfer matrix can be
reduced to a product of $2\times2$ matrices. Then the conductivity and the Fano
factor can be calculated from this product. As an example of the technique,
sinusoidal space dependent strain fields are studied using two different strain
wavelengths. For the bigger wavelength the conductivity is reduced when
compared with the unstrained case, although both conductivities are almost the
same in shape. Whereas, for the smaller wavelength case, the conductivity is
strongly modified. In spite of this, for energies close to the Dirac point
energy, the conductivity and the Fano factor are quite similar to their
unstrained counterpart for the two strain wavelengths here studied.
