Maximum function in matlab

Help Center Help Center. 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. If A is maximum function in matlab multidimensional array, max operates along the first nonsingleton dimension and returns an array of maximum values.

For each letter I have a function that has one peak d is a difference between the position of a specific letter in first word vs its position in the second one :. Define the following expression by using the symbolic max function. I am not a mathematician, maximum function in matlab, forgive me if I'm not able to explain myself clearly.

Help Center Help Center. 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 of A. If A is a multidimensional array, then max A operates along the first dimension of A whose size is greater than 1 , treating the elements as vectors. The size of M in this dimension becomes 1 , while the sizes of all other dimensions remain the same as in A.

For example, create a rational expression where the numerator and the denominator are polynomial expressions. Plotting this expression shows that it has horizontal and vertical asymptotes, a local minimum between -1 and 0, and a local maximum between 1 and 2. By default, when you operate on this expression, results can include both real and imaginary numbers. If you are interested in real numbers only, you can set the permanent assumption that x belongs to the set of real numbers. This allows you to avoid complex numbers in the solutions and it also can improve performance. To find a horizontal asymptote, compute the limit of f for x approaching positive and negative infinities. To find a vertical asymptote of f , find the roots of the polynomial expression that represents the denominator of f. To get an explicit solution for such equations, try calling the solver with the option MaxDegree.

If A is a multidimensional array, then max A operates along the first dimension of A whose size is greater than 1 , treating the elements as vectors. The size of M in this dimension becomes 1 , while the sizes of all other dimensions remain the same as in A. If A is an empty array whose first dimension has zero length, then M is an empty array with the same size as A. If A is a table or timetable, then max A returns a one-row table containing the maximum of each variable. For example, if A is a matrix, then max A,[],2 returns a column vector containing the maximum value of each row. For example, if A is a matrix, then max A,[],[1 2] returns the maximum over all elements in A because every element of a matrix is contained in the array slice defined by dimensions 1 and 2.

The output may have another argument that represents the condition for the symbolic variable. Accepted Answer. Rb: Specify comparison method Specify the real or absolute value method for determining the maximum value of the input by using the ComparisonMethod parameter.

For matrix columns that contain any NaN value, the maximum is NaN. Stephen23 on 11 Dec Search MathWorks. Search Support Clear Filters. Not that this is a good idea, but for an arbitrary number of dimensions:. Off-Canvas Navigation Menu Toggle. If two magnitudes are equal, then max returns the first value. Release Rb. Data Types : fi single double int8 int16 int32 int64 uint8 uint16 uint32 uint Here are two single-peak functions that sum to give 8 local max, only one of them global:. No, overwrite the modified version Yes. Specifying a second input array as a character array gives a warning and will generate an error in a future release.
