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

[val, idx] = max(A, [], 2); The idx part will contain the column number of containing the max element of each row. You can use max() to get the max value. The max function can also return the index of the maximum value in the vector.

**How do you find the max index of an array?**

To get the index of the max value in an array:

- Get the max value in the array, using the Math. max() method.
- Call the indexOf() method on the array, passing it the max value.
- The indexOf method returns the index of the first occurrence of the value in the array or -1 if the value is not found.

**Can you index an array in MATLAB?**

Every variable in MATLABĀ® is an array that can hold many numbers. When you want to access selected elements of an array, use indexing. Using a single subscript to refer to a particular element in an array is called linear indexing.

### How do you find the max value on a graph in MATLAB?

Direct link to this answer

- maxF = max(F); % Find max value over all elements.
- indexOfFirstMax = find(F == maxF, 1, ‘first’); % Get first element that is the max.
- % Get the x and y values at that index.
- maxY = F(indexOfFirstMax);
- maxX = x(indexOfFirstMax);

**What is the index of an array?**

The index indicates the position of the element within the array (starting from 1) and is either a number or a field containing a number.

**How do you find the highest index of a number?**

index() functions to find out the index of the maximum value in a list. Use the enumerate() function to find out the index of the maximum value in a list. Use the numpy. argmax() function of the NumPy library to find out the index of the maximum value in a list.

#### What is an index in MATLAB?

Indexing into a matrix is a means of selecting a subset of elements from the matrix. MATLABĀ® has several indexing styles that are not only powerful and flexible, but also readable and expressive. Indexing is a key to the effectiveness of MATLAB at capturing matrix-oriented ideas in understandable computer programs.

**Does array index start 0 MATLAB?**

In most programming languages, the first element of an array is element 0. In MATLAB, indexes start at 1. Arrays can be sliced by using another array as an index.

**Is MATLAB indexing inclusive?**

For example, return the entire third column of A . In general, you can use indexing to access elements of any array in MATLAB regardless of its data type or dimensions. For example, directly access a column of a datetime array. For higher-dimensional arrays, expand the syntax to match the array dimensions.
