Indexing with a Single Index. Another method for accessing elements of an array is to use only a single index, regardless of the size or dimensions of the array. This method is known as linear indexing. While MATLAB displays arrays according to their defined sizes and shapes, they are actually stored in memory as a single column of elements. How can I index a MATLAB array returned by a function without first assigning it to a local variable? Ask Question Asked 9 years, 2 months ago. MATLAB complains about Unbalanced or unexpected parenthesis or bracket on the first but you have to use the functional form of the indexing operator. When you perform an indexing operation Indexing: vectors in MATLAB are not the same as in every other programming language because the indexing starts from one instead of zero, which means that the first value has the index one. This is the third way of indexing in MATLAB. But there is a big difference in the logic behind them. In case of usual or linear indexing we tell, which indices we do need. In case of logical indexing we use logical values to tell for each element that we need or not need it. So not indices, but logical values are used for indexing. This MATLAB function returns the arrays row and col containing the equivalent row and column subscripts corresponding to the linear indices ind for a matrix of size sz. = ind2sub (sz,ind) returns the Convert a linear index of a 3-D array to a subscript index. Linear Indices A linear index allows use of a single subscript to index into an array, such as A(k). MATLAB ® treats the array as a single column vector with each column appended to the bottom of the previous column. Thus, linear indexing numbers the elements in the columns from top to bottom, left to right.

## In MATLAB®, there are three primary approaches to accessing array elements based on their location (index) in the

When you index into the matrix A using only one subscript, MATLAB treats A as if its elements were strung out in a long column vector, by going down the columns consecutively, as in: 16 5 9 8 12 1 The expression A(14) simply extracts the 14th element of the implicit column vector.

### When you index into the matrix A using only one subscript, MATLAB treats A as if its elements were strung out in a long column vector, by going down the columns consecutively, as in: 16 5 9 8 12 1 The expression A(14) simply extracts the 14th element of the implicit column vector.

Linear Indices A linear index allows use of a single subscript to index into an array, such as A(k). MATLAB ® treats the array as a single column vector with each column appended to the bottom of the previous column. Thus, linear indexing numbers the elements in the columns from top to bottom, left to right. Every variable in MATLAB® is an array that can hold many numbers. When you want to access selected elements of an array, use indexing. For example, consider the 4-by-4 magic square A: There are two ways to refer to a particular element in an array. The most common way is to specify row and column subscripts, such as. Matlab Sect 24 Finding the Length, Size, Sum, and Number of Elements in a Matrix - Duration: 9:44.

So the computed right-hand side has element 1 and 2 copies of the updated element 3 - updated each in the same way, since that's what the code says to do. Remember I said that the MATLAB behavior is as if we placed the right-hand side into a temporary array.

### Suppose I have an array, a = [2 5 4 7]. What is the function returning the maximum value and its index? For example, in my case that function should return 7 as the maximum value and 4 as the index. Write max at the command line and press F1 for help (if on a Windows system, other systems will use another key) and read the documentation.
