Maximum function in matlab

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. 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. For example, max A,[],"includemissing" includes all missing values when computing the maximum. By default, max omits missing values. Create a complex vector and compute its largest element, that is, the element with the largest magnitude.

When we add them together though, we see there are infinite points where the derivative is zero:. Support Answers MathWorks.

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 a multidimensional array, max operates along the first nonsingleton dimension and returns an array of maximum values. If the largest value occurs multiple times, the index of the first occurrence is returned.

Vector I contains the indices to the minimum elements in M.

Edited: Rohit Pappu on 29 Oct More Answers 1. Ra: Specify missing value condition Omit or include all missing values in the input arrays when computing the maximum value by using the "omitmissing" or "includemissing" options. Is that possible? Largest Element Indices. If you specify an empty array for the second argument in order to supply dim or missingflag , the second argument must be of fixed-size and of dimension 0 -by- 0.

Help Center Help Center. Computing the first derivative of an expression helps you find local minima and maxima of that expression. For example, create a rational expression where the numerator and the denominator are polynomial expressions.

If the input is a variable-size array, the length of the dimension to operate along must not be zero at run-time. All variables must have data types that support the calculation. When "linear" is specified, I contains the linear indices of A corresponding to the maximum values. If A is a vector, max A returns the largest element in A. There is any way for a matrix size NxM to get the k maximum element in the whole matrix not in rows or colomns but in only elements. Test Result. Open Live Script.
