| # The kernel function is | |
| # roughtly equivalent to new[:] = np.interp(xnew, xvals, yvals) | |
| # But this is broadcast so that it can be run many, many times | |
| # quickly. | |
| # Call using ynew = interp1d(xnew, xdata, ydata) | |
| # ynew.shape will be xnew.shape | |
| # Also, ydata.shape[-1] must be xdata.shape[-1] | |
| # and if ydata or xdata have ndim greater than 1, the initial dimensions | |
| # must be xnew.shape: |
