deriv1

PURPOSE ^

[b] = deriv1(a, nlin, npix, fil)

SYNOPSIS ^

function [b] = deriv1(a, nlin, npix, fil)

DESCRIPTION ^

 [b] = deriv1(a, nlin, npix, fil)
  Computes first derivative via FIR (1xn) filter
  Edge effects are suppressed and vector size is preserved
  Filter is applied in the npix direction only
   a = (nlin, npix) data array
   fil = array of filter coefficients, eg [-0.5 0.5]
   b = output (nlin, npix) data array
