How do you plot a graph in Matlab?

MATLAB - Plotting

1. Define x, by specifying the range of values for the variable x, for which the function is to be plotted.
2. Define the function, y = f(x)
3. Call the plot command, as plot(x, y)

What is plot Matlab?

plot( X , Y ) creates a 2-D line plot of the data in Y versus the corresponding values in X . ... The plot function plots columns of Y versus columns of X . If one of X or Y is a vector and the other is a matrix, then the matrix must have dimensions such that one of its dimensions equals the vector length.

How do you plot a 3d figure in Matlab?

Creating 3-D Plots

1. z = peaks(25); figure mesh(z)
2. surf(z)
3. surfl(z) colormap(pink) % change color map shading interp % interpolate colors across lines and faces.
4. contour(z,16) colormap default % change color map.

What is 3d plot in Matlab?

Three-dimensional plots typically display a surface defined by a function in two variables, z = f(x,y) . To evaluate z, first create a set of (x,y) points over the domain of the function using meshgrid . [X,Y] = meshgrid(-2:. 2:2); Z = X . ... Then, create a surface plot.

How do you plot a 3d sine wave in Matlab?

Direct link to this answer

1. surf(bsxfun(@(x,y)sin(x)+sin(y),-pi:0.

   What is the formula for a sine wave?

   Sine Wave. ... A general form of a sinusoidal wave is y(x,t)=Asin(kx−ωt+ϕ) y ( x , t ) = A sin ( kx − ω t + ϕ ) , where A is the amplitude of the wave, ω is the wave's angular frequency, k is the wavenumber, and ϕ is the phase of the sine wave given in radians.

   What does sine wave mean?

   A sine wave is a geometric waveform that oscillates (moves up, down or side-to-side) periodically, and is defined by the function y = sin x. In other words, it is an s-shaped, smooth wave that oscillates above and below zero.

   Why is AC a sine wave?

   The sine wave is a consequence of the way the AC is produced. ... If current is positive they move in one if current is negative they move in the other direction, but not representing any sinusoidal motion. The sinusoidal current comes from the amount of electrons - this just as a sidenote.

   What needs pure sine wave?

   Some devices and appliances that require a pure sine inverter are: Microwaves. Laser printers. Variable speed tools.

   Is light a sine wave?

   Light is represented as a sine wave because it's light of a single frequency so it's the simplist thing to draw on paper. Laser light is a single frequency. White light however is light made up of the sum of different wavelengths of light.

   What shape is a light wave?

   Waves can take on many shapes. One of the most common wave shapes is called a sine wave, shown below. Light waves are one of many types of waves in nature shaped like sine waves. Their repeating pattern allows us to classify them based on their wavelength.

   What does a sine graph look like?

   To graph the sine function, we mark the angle along the horizontal x axis, and for each angle, we put the sine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that varies from +1 to -1. Curves that follow this shape are called 'sinusoidal' after the name of the sine function.

   What kind of wave is light?

   Light waves are just one type of electromagnetic wave. Other electromagnetic waves include the microwaves in your oven, radio waves, and X-rays. Light waves are regarded as a varying electric field (E) coupled with a varying magnetic field (B), at right angles to each other and to the direction of travel.

   Is light a particle?

   Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass.

   What causes a light wave?

   We have learned that refraction occurs as light passes across the boundary between two media. The light wave not only changes directions at the boundary, it also speeds up or slows down and transforms into a wave with a larger or a shorter wavelength. ...

   Why is light an electromagnetic wave?

   Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light. ... So, Maxwell's equations do say that light is a wave.

   Is an electromagnetic wave?

   Definition of 'Electromagnetic Waves' Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields. ... They are hence known as 'electromagnetic' waves.

   Is current an electromagnetic wave?

   2 Answers. Electric current is the movement of electric charge through a conductor. ... An electromagnetic wave does not require a conductor. Electromagnetic waves are created by moving electric charges, but once created, they can propagate through a vacuum.

   What are the 7 types of electromagnetic waves?

   The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

   What is the most important electromagnetic wave?

   The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves.

   What are 3 examples of electromagnetic energy?

   They include:

   • Radio Waves.
   • TV waves.
   • Radar waves.
   • Heat (infrared radiation)
   • Light.
   • Ultraviolet Light (This is what causes Sunburns)
   • X-rays (Just like the kind you get at the doctor's office)
   • Short waves.
