# scipy.interpolate.BarycentricInterpolator.set_yi

`BarycentricInterpolator.``set_yi`(yi)

  Update the y values to be interpolated

  The barycentric interpolation algorithm requires the calculation of weights, but these depend only on the xi. The yi can be changed at any time.

  Parameters : | yi : array-like N by R The y coordinates of the points the polynomial should pass through; if R>1 the polynomial is vector-valued. If None the y values will be supplied later.
