How do you return the index of the max value in Matlab?

How do you return the index of the max value 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 index?

How to find the index of the max value in a list in Python

1. number_list = [1, 2, 3]
2. max_value = max(number_list) Return the max value of the list.
3. max_index = number_list. index(max_value) Find the index of the max value.
4. print(max_index)

How do you return an 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 position in Matlab?

Direct link to this answer

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 find Max in MATLAB?

M = max( A ) returns the maximum elements of an array.

1. If A is a vector, then max(A) returns the maximum of A .
2. If A is a matrix, then max(A) is a row vector containing the maximum value of each column.

How do you find peak value in MATLAB?

Use findpeaks with default settings to find the peaks of the signal and their locations. [pks,locs] = findpeaks(PeakSig,x); Plot the peaks using findpeaks and label them. Sort the peaks from tallest to shortest.

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

Return the Min or Max Value Using a Lookup in Excel – INDEX MATCH

1. Type =INDEX(
2. Select the column that contains the data you want to return, in this case the Site column.
3. Type a comma to go to the next argument and then type MATCH(
4. Now, type MAX(

How do you find the maximum value of a matrix in MATLAB?

Direct link to this answer

1. A = randi(100,7,6); % your matrix.
2. v = max(A(:)); % value.
3. [ii,jj] = find(A == v); % row and column number.

How do you find the maximum point on a graph?

If you have the graph, or can draw the graph, the maximum is just the y value at the vertex of the graph. If you are unable to draw a graph, there are formulas you can use to find the maximum. If you are given the formula y = ax2 + bx + c, then you can find the maximum value using the formula max = c – (b2 / 4a).

How can I find the maximum value and its index in?

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. To get this, assign the result of the call to max to a two element vector instead of just a single variable.

How to find the maximum value of a in MATLAB?

[M,I] = max ( ___) also returns the index into the operating dimension that corresponds to the maximum value of A for any of the previous syntaxes. M = max (A, [],’all’) finds the maximum over all elements of A. This syntax is valid for MATLAB ® versions R2018b and later.

How to get the largest element index in MATLAB array?

Use the second output argument of the max function: index = find(array == max(array), 1); which returns the index of the first element that is equal to the maximum value. You can fiddle with the options of find if you want the last element instead, etc.

How does a linear index work in MATLAB?

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.
