stamm

Format:

stamm( vector_id)

Result:

Vector

Description:

Returns the integral function of a SCAN. It is calculated using this formula:

$$y_j = \sum_{i=1}^{i=j}{0.5(y_i + y_{i-1})(x_i - x_{i-1})}$$

Note that the integral of a SCAN is evaluated by the scalar function integral().

e.g.:

SPECTRA> calc the_same = ableitung(stamm(bpu1))
