Can you plot imaginary numbers in Matlab?

If the input to the Matlab plot command is a vector of complex numbers, the real parts are used as the x-coordinates and the imaginary parts as the y-coordinates. Plotting the real and imaginary parts separately will work. Matlab recognises the input is a complex number and does some of the work for you.

How do you plot imaginary points in Matlab?

Plot One Complex Input With complex inputs, plot(z) is equivalent to plot(real(z),imag(z)) , where real(z) is the real part of z and imag(z) is the imaginary part of z . Define z as a vector of eigenvalues of a random matrix. z = eig(randn(20)); Plot the imaginary part of z versus the real part of z .

How do you graph imaginary numbers?

How To: Given a complex number, represent its components on the complex plane.

1. Determine the real part and the imaginary part of the complex number.
2. Move along the horizontal axis to show the real part of the number.
3. Move parallel to the vertical axis to show the imaginary part of the number.
4. Plot the point.

How do you GEt imaginary parts in Matlab?

Y = imag( Z ) returns the imaginary part of each element in array Z .

How to create an imaginary unit in MATLAB?

Create a complex vector from two 4-by-1 vectors of real numbers. z is a 4-by-1 complex vector. Create a complex scalar representing a complex vector with radius, r, and angle from the origin, theta. Real component of a complex scalar, specified as a scalar. Imaginary component of a complex scalar, specified as a scalar.

How to plot the imaginary part of a matrix?

With complex inputs, plot (z) is equivalent to plot (real (z),imag (z)), where real (z) is the real part of z and imag (z) is the imaginary part of z. Define z as a vector of eigenvalues of a random matrix. z = eig (randn (20)); Plot the imaginary part of z versus the real part of z.

How to plot real and imaginary parts of sign function?

Plot real and imaginary parts of the sign function over and . First, create a mesh of values over -3 < x < 3 and -3 < y < 3 using meshgrid. Then create complex numbers from these values using z = x + 1i*y. Find the real and imaginary parts of the sign function of z. Plot the real and imaginary parts.

How do you plot complex numbers in MATLAB?

It is useful to plot complex numbers as points in the complex plane and also to plot function of complex variables using either contour or surface plots. If the input to the Matlab plot command is a vector of complex numbers, the real parts are used as the x-coordinates and the imaginary parts as the y-coordinates.
