# How do you access elements in a cell in MATLAB?

Access the contents of cells–the numbers, text, or other data within the cells–by indexing with curly braces. For example, to access the contents of the last cell of C , use curly braces. last is a numeric variable of type double , because the cell contains a double value.

## How do you access elements in a cell in MATLAB?

## How do you find data in an array in MATLAB?

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

How do you access elements in an array in MATLAB?

To access elements in a range of rows or columns, use the colon . For example, access the elements in the first through third row and the second through fourth column of A . An alternative way to compute r is to use the keyword end to specify the second column through the last column.

How do I use Isnumeric in MATLAB?

TF = isnumeric( A ) returns logical 1 ( true ) if A is an array of numeric data type. Otherwise, it returns logical 0 ( false ). Numeric types in MATLAB® include: int8 , int16 , int32 , int64 , uint8 , uint16 , uint32 , uint64 , single , and double . For more information, see Integer Classes and Floating-Point Numbers.

### What is a cell array in MATLAB?

A cell array is a data type with indexed data containers called cells, where each cell can contain any type of data. Cell arrays commonly contain either lists of text, combinations of text and numbers, or numeric arrays of different sizes. Refer to sets of cells by enclosing indices in smooth parentheses, () .

### How do you make a cell array in MATLAB?

When you have data to put into a cell array, create the array using the cell array construction operator, {} . Like all MATLAB® arrays, cell arrays are rectangular, with the same number of cells in each row. myCell is a 2-by-3 cell array. You also can use the {} operator to create an empty 0-by-0 cell array.

How do I find a specific value in an array?

Use filter if you want to find all items in an array that meet a specific condition. Use find if you want to check if that at least one item meets a specific condition. Use includes if you want to check if an array contains a particular value. Use indexOf if you want to find the index of a particular item in an array.

How do I find a specific value in MATLAB?

To find a specific integer value, use the == operator. For instance, find the element equal to 13 in a 1-by-10 vector of odd integers. To find a noninteger value, use a tolerance value based on your data. Otherwise, the result is sometimes an empty matrix due to floating-point roundoff error.

## How do you find the index value in MATLAB?

Description. k = find( X ) returns a vector containing the linear indices of each nonzero element in array X . If X is a vector, then find returns a vector with the same orientation as X . If X is a multidimensional array, then find returns a column vector of the linear indices of the result.

## How do you find the index of a value in MATLAB?

In MATLAB the array indexing starts from 1. To find the index of the element in the array, you can use the find() function. Using the find() function you can find the indices and the element from the array. The find() function returns a vector containing the data.
