B = permute( A , dimorder ) **rearranges the dimensions of an array in the order specified by the vector dimorder** . For example, permute(A,[2 1]) switches the row and column dimensions of a matrix A . In general, the ith dimension of the output array is the dimension dimorder(i) from the input array.

## What is Permute Matlab?

permute (MATLAB Functions) B = permute(A,order) **rearranges the dimensions of A so that they are in the order specified by the vector order** . B has the same values of A but the order of the subscripts needed to access any particular element is rearranged as specified by order . All the elements of order must be unique.

## How do you concatenate in Matlab?

You can **use the square bracket operator []** to concatenate. For example, [A,B] or [A B] concatenates arrays A and B horizontally, and [A; B] concatenates them vertically.

## What is the purpose of Randperm?

p = randperm(n) **returns a random permutation of the integers 1:n** . The randperm function calls rand and therefore changes rand 's state. or it might be some other permutation of 1:6 .

## How is Randperm different from Rand?

The main difference between randi and randperm is that **randi contains an array of values that can be repeated but randperm contains an array of integers that are unique**. It is denoted using randperm().

### How does Randi work in Matlab?

X = randi( imax , sz ) **returns an array where size vector sz defines size(X)** . For example, randi(10,[3,4]) returns a 3-by-4 array of pseudorandom integers between 1 and 10. X = randi( imax , typename ) returns a pseudorandom integer where typename specifies the data type.

### What does concatenate mean in Matlab?

Concatenating Matrices

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**.

### What is concatenating a matrix?

Matrix concatenation is **the process of joining one or more matrices to make a new matrix**. ... The expression C = [A B] horizontally concatenates matrices A and B . The expression C = [A; B] vertically concatenates them.

### How do you use DISP?

disp( X ) displays **the value of variable X without printing** the variable name. Another way to display a variable is to type its name, which displays a leading “ X = ” before the value. If a variable contains an empty array, disp returns without displaying anything.

### What is meant by Idempotent Matrix?

In linear algebra, an idempotent matrix is **a matrix which, when multiplied by itself, yields itself**. That is, the matrix is idempotent if and only if . For this product to be defined, must necessarily be a square matrix.

### What is the meaning Permute?

transitive verb. : **to change the order or arrangement of especially** : to arrange in all possible ways.

### WHAT IS A if B is a singular matrix?

If A is a square matrix, B is a singular matrix of same order, then for a positive integer n,(A^-1BA)^n equals. >>Class 12. >>Maths. >>Matrices. >>Inverse of a Matrix.

### What is Bsxfun MATLAB?

The bsxfun function **expands the vectors into matrices of the same size**, which is an efficient way to evaluate fun for many combinations of the inputs.

### How do you use Permute in MATLAB?

B = permute( A , dimorder ) **rearranges the dimensions of an array in the order specified by the vector dimorder** . For example, permute(A,[2 1]) switches the row and column dimensions of a matrix A . In general, the ith dimension of the output array is the dimension dimorder(i) from the input array.

### How do you concatenate a matrix?

You can concatenate two matrices to create a larger matrix. **The pair of square brackets '[]' is** the concatenation operator. When you concatenate two matrices by separating those using commas, they are just appended horizontally. It is called horizontal concatenation.

### Can you plot a matrix in Matlab?

plotmatrix( X , Y ) creates a matrix of subaxes containing scatter plots of the columns of X against the columns of Y . If X is p-by-n and Y is p-by-m, then plotmatrix produces an n-by-m matrix of subaxes.

### What is Strcat in MATLAB?

s = strcat( s1,...,sN ) **horizontally concatenates the text in its input arguments**. Each input argument can be a character array, a cell array of character vectors, or a string array. If any input is a string array, then the result is a string array.

### Why Randi is used in Matlab?

X = randi( imax , n ) **returns an n -by- n matrix of pseudorandom integers drawn from the discrete uniform distribution on the interval [ 1 , imax** ]. ... For example, randi(10,3,4) returns a 3-by-4 array of pseudorandom integers between 1 and 10.
