## Can you plot in MATLAB?

Plot Multiple Lines By default, MATLAB clears the figure before each plotting command. Use the figure command to open a new figure window. You can plot multiple lines using the hold on command. Until you use hold off or close the window, all plots appear in the current figure window.

### How do you create a convolution in MATLAB?

w = conv( u,v ) returns the convolution of vectors u and v . If u and v are vectors of polynomial coefficients, convolving them is equivalent to multiplying the two polynomials. w = conv( u,v , shape ) returns a subsection of the convolution, as specified by shape .

**Which of the following command can be used in MATLAB to perform convolution?**

Explanation: The conv2() command is defined in MATLAB to perform 2d convolution.

**What is convolution example?**

It is defined as the integral of the product of the two functions after one is reversed and shifted. For example, periodic functions, such as the discrete-time Fourier transform, can be defined on a circle and convolved by periodic convolution.

## What is Heaviside function in Matlab?

H = heaviside( x ) evaluates the Heaviside step function (also known as the unit step function) at x . The Heaviside function is a discontinuous function that returns 0 for x < 0 , 1/2 for x = 0 , and 1 for x > 0 .

### What is a MEX file in Matlab?

A MEX file is a function, created in MATLAB, that calls a C/C++ program or a Fortran subroutine. A MEX function behaves just like a MATLAB script or function. To call a MEX function, use the name of the MEX file, without the file extension. The MEX file contains only one function or subroutine.

**How to perform a convolution in MATLAB?**

Now convolution can be performed in the matlab using a command conv, conv is an abbreviation of convolution that is the 1 st 4 words of convolution conv of now place 1 st signal name y1 and comma for separated place 2 nd signal name h1. And the convolution result we stored in X variable.

**How to plot the central part of a convolution?**

Your code will give you a vector of length length (y1)+length (y2)-1, so you’ll get an error if you plot it against x (which is presumably the same length as y1 and y2). Instead, use which gives you the central part of the convolution of the same size as y1. Then you’ll be able to plot it. Thanks a lot! Sign in to comment.

## How to calculate the convolution of two signal without using Conv?

Hi everyone, i was wondering how to calculate the convolution of two sign without Conv ();. I need to do that in order to show on a plot the process. i know that i must use a for loop and a sleep time, but i dont know what should be inside the loop, since function will come from a pop-up menu from two guides. (guide’ code are just ready);

### How to calculate the convolution of a vector?

w = conv(u,v) returns the convolution of vectors u and v. If u and v are vectors of polynomial coefficients, convolving them is equivalent to multiplying the two polynomials. w = conv(u,v,shape) returns a subsection of the convolution, as specified by shape.

**Which is an example of a convolution in MATLAB?**

Create two vectors and convolve them. The length of w is length (u)+length (v)-1, which in this example is 9. Create two vectors. Find the central part of the convolution of u and v that is the same size as u. w has a length of 7. The full convolution would be of length length (u)+length (v)-1, which in this example would be 10.

Your code will give you a vector of length length (y1)+length (y2)-1, so you’ll get an error if you plot it against x (which is presumably the same length as y1 and y2). Instead, use which gives you the central part of the convolution of the same size as y1. Then you’ll be able to plot it. Thanks a lot! Sign in to comment.

**How to calculate the length of a convolution?**

Full convolution (default). Central part of the convolution of the same size as u. Only those parts of the convolution that are computed without the zero-padded edges. Using this option, length (w) is max (length (u)-length (v)+1,0) , except when length (v) is zero. If length (v) = 0, then length (w) = length (u).

## How to plot a three signal in MATLAB?

For plotting a three signals, we 1 st plot figure 1 in signal figure we plot a three signals using a subplot function. subplot (3,1,1) so 1 st we plot a y1 w.r.t n1, so plotting a signal we use stem function, stem is used to plot a discrete time signal, so we take stem (n1, y1).
