Plot the azimuth pattern of the array. c = physconst('LightSpeed'); pattern(array,fc,[-180:180],0,'PropagationSpeed',c,...'CoordinateSystem','polar','Type','powerdb','Normalize',true) This example shows how to find and plot the positions of the elements of a 5-row-by-6-column UR...
patternMultiply(___,Name=Value) uses additional options specified by one or more Name-Value Arguments after all the other input arguments. example [fieldval,azimuth,elevation] = patternMultiply(array,frequency) returns the field value such as the directivity of the lossless array in dBi or gain...
