The function accepts both real and complex inputs. The result is 0, so this is the x-intercept of the log10 function. The size of the array can be m-by-1 or 1-by-m. MATLAB accesses alpha values by their index in the array. You clicked a link that corresponds to this MATLAB command: Run the command by entering it in the MATLAB Command Window. 1 [1 3 5] Logical vector Python also has an inspect module For real values such that z = abs(z).*exp(i*theta).
