How do you find the magnitude and phase of a complex number?
|a + bj| = √a2 + b2. The angle or phase or argument of the complex number a + bj is the angle, measured in radians, from the point 1 + 0j to a + bj, with counterclockwise denoting positive angle. The angle of a complex number c = a + bj is denoted c: c = arctanb/a.
How do you find the magnitude of a complex number in Matlab?
Y = abs( X ) returns the absolute value of each element in array X . If X is complex, abs(X) returns the complex magnitude.
How to plot phase of complex number in matlab?
theta = angle( z ) returns the phase angle in the interval [-π,π] for each element of a complex array z . The angles in theta are such that z = abs(z). *exp(i*theta) .
