How do you find the max value in an array in MATLAB?

Description. M = max( A ) returns the maximum elements of an array. If A is a vector, then max(A) returns the maximum of A . If A is a matrix, then max(A) is a row vector containing the maximum value of each column.

How do you find the maximum of a surface plot in MATLAB?

Direct link to this comment Idx = find((Z(:) == max(Z(:)))); [ZmaxRow,ZmaxCol] = ind2sub(size(Z), Idx); That will return all the values that equal the maximum, and their coordinates.

How do you 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)”.

How do you find the max value of an array?

To find the maximum value in an array:

  1. Assign the first (or any) array element to the variable that will hold the maximum value.
  2. Loop through the remaining array elements, starting at the second element (subscript 1). When a larger value is found, that becomes the new maximum.

How do you find the maximum 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 max in Python?

Use max() to Find Max Value in a List of Strings and Dictionaries. The function max() also provides support for a list of strings and dictionary data types in Python. The function max() will return the largest element, ordered by alphabet, for a list of strings. The letter Z is the largest value, and A is the smallest.

How do you find the max index of an array?

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

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

How do you plot maximum and minimum in MATLAB?

Use Semiautomatic Axis Limits. Set the maximum x-axis limit to 0 and the minimum y-axis limit to -1. Let MATLAB choose the other limits. For an automatically calculated minimum or maximum limit, use -inf or inf , respectively.

How do you find a specific value in an array?

Use filter if you want to find all items in an array that meet a specific condition. Use find if you want to check if that at least one item meets a specific condition. Use includes if you want to check if an array contains a particular value. Use indexOf if you want to find the index of a particular item in an array.
