## How do you get the position of an element in a matrix in Matlab?

Direct link to this answer

- You can use the “find” function to return the positions corresponding to an array element value. For example:
- To get the row and column indices separately, use:
- If you only need the position of one occurrence, you could use the syntax “find(a==8,1)”.

**How do you call a specific part of a matrix in Matlab?**

The most common way is to explicitly specify the indices of the elements. For example, to access a single element of a matrix, specify the row number followed by the column number of the element. e is the element in the 3,2 position (third row, second column) of A .

**How do you find the order of a matrix in Matlab?**

B = sort( A , dim ) returns the sorted elements of A along dimension dim . For example, if A is a matrix, then sort(A,2) sorts the elements of each row. B = sort(___, direction ) returns sorted elements of A in the order specified by direction using any of the previous syntaxes.

### How do you select part of a matrix?

You should therefore use a comma to separate the rows you want to select from the columns. For example: my_matrix[1,2] selects the element at the first row and second column. my_matrix[1:3,2:4] results in a matrix with the data on the rows 1, 2, 3 and columns 2, 3, 4.

**How do you find the part of an array in MATLAB?**

To refer to multiple elements of an array, use the colon ‘:’ operator, which allows you to specify a range of elements using the form ‘start:end’. The colon alone, without start or end values, specifies all the elements in that dimension.

**How do you change the order of a matrix in MATLAB?**

Create a matrix A and sort each column of A in ascending order. Sort each row in descending order. The second argument value 2 specifies that you want to sort row-wise. To sort entire rows or columns relative to each other, use the sortrows function.

## What is selection of matrix?

DECISION MATRIX/SELECTION MATRIX What it is: A decision matrix is a chart that allows a team or individual to systematically identify, analyze, and rate the strength of relationships between sets of information.

**What do colons mean in MATLAB?**

The colon(:) is one of the most useful operator in MATLAB. It is used to create vectors, subscript arrays, and specify for iterations. If you want to create a row vector, containing integers from 1 to 10, you write − 1:10.
