How to create a vector with the same value in matlab

How do you repeat a value in a vector in Matlab?

u = repelem( v , n ) , where v is a scalar or vector, returns a vector of repeated elements of v . If n is a scalar, then each element of v is repeated n times. The length of u is length(v)*n .

How do I create an array of the same number in Matlab?

Accepted Answer

You can try using ‘ones’ function to create such a matrix. Following is an example to create a matrix X=[300,300,300,300,300,300,600,600,600,600,600,600] X=[300*ones(1,6),600*ones(1,6)];

How do I concatenate a vector in Matlab?

You can also use square brackets to join existing matrices together. This way of creating a matrix is called concatenation. For example, concatenate two row vectors to make an even longer row vector. To arrange A and B as two rows of a matrix, use the semicolon.

What is a concatenated vector?

Vector Concatenate, Matrix Concatenate. Concatenate input signals of same data type to create contiguous output signal.

How do you call a function in Matlab?

Calling Functions
  1. Open Live Script. MATLAB® provides a large number of functions that perform computational tasks.
  2. ans = 5. If there are multiple input arguments, separate them with commas:
  3. ans = 1×3 10 6 5. Return output from a function by assigning it to a variable:
  4. maxA = 5.
  5. [maxA,location] = max(A)
  6. location = 3.
  7. hello world.
  8. clc.

What is a function in Matlab?

A function is a group of statements that together perform a task. In MATLAB, functions are defined in separate files. Functions can accept more than one input arguments and may return more than one output arguments.

How do you call a function?

How do I call a function?
  1. Write the name of the function.
  2. Add parentheses () after the function’s name.
  3. Inside the parenthesis, add any parameters that the function requires, separated by commas.
  4. End the line with a semicolon ; .

What are Matlab scripts?

The simplest type of MATLAB® program is called a script. A script is a file that contains multiple sequential lines of MATLAB commands and function calls. You can run a script by typing its name at the command line.

How do I create a script file?

Let us understand the steps in creating a Shell Script:
  1. Create a file using a vi editor(or any other editor). Name script file with extension . sh.
  2. Start the script with #! /bin/sh.
  3. Write some code.
  4. Save the script file as filename.sh.
  5. For executing the script type bash filename.sh.

What is the difference between a script file and a function Matlab?

Scripts versus Functions

Scripts are m-files containing MATLAB statements. MATLABfunctions” are another type of m-file. The biggest difference between scripts and functions is that functions have input and output parameters. Script files can only operate on the variables that are hard-coded into their m-file.

Can you put a function in a script Matlab?

Starting in R2016b, MATLAB® scripts, including live scripts, can contain code to define functions. These functions are called local functions. Local functions are useful if you want to reuse code within a script. By adding local functions, you can avoid creating and managing separate function files.
