NMRPipe Processing Functions DX performs a numerical derivative calculation on each vector. If the current dimension is complex, the real and imaginary parts are treated separately. For an N-point data vector y[0] ... y[N-1] the derivative dy[i] is calculated as: dy[0] = y[1] - y[0]for the first point. dy[i] = y[i+1] - y[i-1]for the interior points, and dy[N] = y[N] - y[N-1]for the last point. The nmrPipe function INTEG performs the numerical integral function, the complementary function to DX. |
