# How do you find the MAX index in MATLAB?

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

You can use max() to get the max value. The max function can also return the index of the maximum value in the vector. To get this, assign the result of the call to max to a two element vector instead of just a single variable. Here, 7 is the largest number at the 4th position(index).

### How do you find the maximum value of an index?

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.

How do you find the maximum value in a row in MATLAB?

m=max(I,[],2);

What is the max function in MATLAB?

Description. example. M = max( A ) returns the largest elements along different dimensions of fi array A . If A is a vector, max(A) returns the largest element in A . If A is a matrix, max(A) treats the columns of A as vectors, returning a row vector containing the maximum element from each column.

## What is the index in MATLAB?

Indexing into a matrix is a means of selecting a subset of elements from the matrix. MATLAB® 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.

### How do I index a specific row 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 maximum value of a row in a matrix?

1. Although it’s too late, might be helpful for others.
2. row_max = max(M’); %finds the maximum value in each row by taking transpose of matrix M.
3. my_max_val = col_max(1,4) % gives the maximum value in row 4.
4. %For the maximum value in columns 2 and 3:
5. col_max = max(M);
6. col_max1 = col_max(1,2)

How do you find the extrema of a function in MATLAB?

To add the Find Local Extrema task to a live script in the MATLAB Live Editor:

1. On the Live Editor tab, click Task and select the Find Local Extrema icon .
2. In a code block in the live script, type a relevant keyword, such as extrema or find . Select Find Local Extrema from the suggested command completions.

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

k = find( X ) returns a vector containing the linear indices of each nonzero element in array X .

1. If X is a vector, then find returns a vector with the same orientation as X .
2. If X is a multidimensional array, then find returns a column vector of the linear indices of the result.

### How do you find indices?

How do I find a specific value 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)”.

What is the command to find maximum and minimum values in a column row or matrix?

We have made use of the max() function which is used to find the maximum element present in an object. This object can be a Vector, a list, a matrix, a data frame, etc. The “which()” function is used to get the index or position of the value which satisfies the given condition.

## How to get the index of the maximum value in vector?

The max function can also return the index of the maximum value in the vector. To get this, assign the result of the call to max to a two element vector instead of just a single variable.

### How to get the maximum value of a column in MATLAB?

Accepted Answer. The “min” and “max” functions in MATLAB return the index of the minimum and maximum values, respectively, as an optional second output argument. For example, the following code produces a row vector ‘M’ that contains the maximum value of each column of ‘A’, which is 3 for the first column and 4 for the second column.

How do I get the index of the minimum and maximum values?

Sign in to answer this question. The “min” and “max” functions in MATLAB return the index of the minimum and maximum values, respectively, as an optional second output argument.

How to get the maximum value of a function?

For example, in my case that function should return 7 as the maximum value and 4 as the index. Show activity on this post. The function is max. To obtain the first maximum value you should do val is the maximum value and idx is its index. Show activity on this post. I is the index of A (:) containing the largest element.
