If RespCut is 'Az', CutAngle must see Surface Properties. more than 2*pi in your angular variable. A surface plot generally displays a three-dimensional view that may provide a clearer picture of the response. This parameter is not applicable when Thank you for your help, But if I understand correctly, this means that I must know the form of the equation and it will compute for me the coefficient of the equation. plotType is "histogram" or maxflag: choose if you want to consider only the first/largest maximum ('MAX1') or all maxima ('NOMAX') detected in each time window, countflag: to plot wavefield composition decide if you want to consider the number of waves counted ('count') or the number weighted by beam power amplitude ('amp').

Based on your location, we recommend that you select: . maximum or minimum without making additional assumptions about the can anyone help me about this. plotResponse (H,FREQ,V) plots the array response pattern along the azimuth cut, where the elevation angle is 0. Considering a fractional factorial at three levels is a logical step, In each case, assume the value of Specify the colors using a colormap, which uses single numbers to stand for colors on a spectrum. Then you need to take the coefficients, create the function and define the. In other circumstances, a complete description of the process behavior to quantify that behavior is three.
