srcb2 = p_bf*data2;  \end{verbatim}  using the following formula from the lecture slides  $$P_{BF,\theta} = \dfrac{(C_\mathrm{d}^{-1} L_\theta)^T}{L_\theta^T C_\mathrm{d}^{-1} L_\theta}$$, L_\theta},$$  where $L_\theta$ is the lead field vector of channel $\theta$.  We wanted to visualize the source estimates as a function of time. We achieved this with the following script:
