How do you find the max value position 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 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 index?

Use max() and list. index() to find the max value in a list

  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 find the position of a value in a matrix 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 does abs do in MATLAB?

Description. Y = abs( X ) returns the absolute value of each element in array X . If X is complex, abs(X) returns the complex magnitude.

What does Max do in MATLAB?

C = max(A) returns the largest elements along different dimensions of an array. 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 max in pandas?

idxmax() function returns index of first occurrence of maximum over requested axis. While finding the index of the maximum value across any index, all NA/null values are excluded. Example #1: Use idxmax() function to function to find the index of the maximum value along the index axis.

What does find function do in Matlab?

The find() function in MATLAB is used to find the indices and values of non-zero elements or the elements which satisfy a given condition. The relational expression can be used in conjunction with find to find the indices of elements that meet the given condition. It returns a vector that contains the linear indices.

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 find maximum value and its location?

Sign in to answer this question. You are very close. you are finding the value , but not the index , of the maximum. If you call max () with two output arguments, then you will also get the index. you are using a function that converts a linear index to (x,y) coordinates.

How to find the maximum value of a column in Excel?

M = max (A, [],dim) returns the maximum element along dimension dim. For example, if A is a matrix, then max (A, [],2) is a column vector containing the maximum value of each row. M = max (A, [],nanflag) specifies whether to include or omit NaN values in the calculation.

How to find the max value in a vector?

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. e.g. z is your array,
