The above code for Trapezoidal method in MATLAB has been programmed to find the area under the curve f(x) = x 2 in the interval [1, 2]. a more complex problem, high–resolution 2D DOA estima-tion. The parameter mu defines where to estimate the value on the interpolated line, it is 0 at the first point and 1 and the second point. 1109/icecds. Hence we can generate pairs of random numbers $(x_i,y_i) \in [-1,1]$. Infinite values in x are assumed to correspond to a point mass at +/-Inf and the density estimate is of the sub-density on (-Inf, +Inf). The Octave syntax is largely compatible with Matlab. Via computer simulation on 2D-DOA estimation, we have shown that the proposed method revealsazimuth-independent performance compared to the 2D-ESPRIT. PCP_techrep2010_buffy. Another cross-correlation-based 2D DOA estimation (CODE) algorithm was recently proposed  based on an L-shaped array composed of two uniform linear arrays (ULAs). The two key modifications were the separation of the two different sets of wing element panels and the subsequent addition of a second Kutta condition. Peak detection in Python [Eli Billauer]. The parameter mu defines where to estimate the value on the interpolated line, it is 0 at the first point and 1 and the second point. I went through the math and understand I have to use the correlation, but when I implement it in Matlab I clearly do some mistakes and get a correlation that has only one peak, in the center (in time) of the signal.
