realReal part of complex number signSign function (signum function) unwrapShift phase angles Topics Plot Complex Numbers Plot the imaginary part versus the real part of complex numbers. Why did you choose this
My idea was then to convert this complex value that has a relative phase to my input signal into some real signal with same amplitude, but showing a time shift matching the argument of my complex number, but I can't figure it out. Any suggestions ? I know of the transport delay / ...
Plot the fifth roots of unity in the polar coordinates by using polarplot. Use the angle function to return the phase angles of the complex roots, and use the abs function to return the absolute values or radii of the complex roots. Get polarplot(angle(z),abs(z),"o") You can also...
If any element of A(:,1) is not equal to 1, then phasez normalizes the filter coefficients by A(:,1). In this case, A(:,1) must be nonzero. Data Types: double | single Complex Number Support: Yes g— Scale values scalar | vector Since R2024b Scale values, specified as a re...

If scale is 1, then Hankel functions of the first kind Hν(1)(z) are scaled by e−iZ, and Hankel functions of the second kind Hν(2)(z) are scaled by e+iZ. exampleExamples collapse all Modulus and Phase of Hankel Function Copy Code Copy Command Generate the contour plots of the...
Specify the time duration of each chip in a phase-coded waveform as a positive scalar. Units are seconds. For this waveform, the pulse duration is equal to the product of the chip width and number of chips. The value of this property must satisfy these constraints: ...
abs, real, imag, angle, conj: These functions perform operations on complex numbers such as finding the absolute value, real part, imaginary part, phase angle, and conjugate. floor, ceil, round, fix: These functions perform rounding operations on numbers. max, min, sort, mean, median, mode...
Input array, specified as a symbolic expression, vector, or matrix of symbolic expressions. IfAis complex, thenmin(A)returns the complex number with the smallest magnitude. If magnitudes are equal, thenmin(A)returns the value with the smallest magnitude and the smallest phase angle. ...
