For an input A that contains symbolic expression, the symbolic max function returns an unevaluated expression that is reduced by eliminating arguments that do not represent maximum values. The output may have another argument that represents the condition for the symbolic variable. For example, max A,[],'includenan' includes all NaN values in A while max A,[],'omitnan' ignores them.

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. The output, M , is a row vector that contains the largest elements from each column of A. Vector I contains the indices to the minimum elements in M.

If size A,dim is 0 , then max A,dim returns an empty array with the same size as A. Create a matrix and return the largest value between each of its elements compared to a scalar. Select the China site in Chinese or English for best site performance. Note that there can be the max value at more than one location. If A has elements with equal real parts, then use imag A to break ties. Ran in:. Find the value of f x which corresponds to the maximum over the given interval and print it out. Usage notes and limitations: Index output is not supported for distributed tabular inputs. Vote 2. I got this max value, but I would like to see just how big my variable is. 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. Dimension dim indicates the dimension whose length reduces to 1.

The max function returns the largest element in output x and the index of that element in output y. Walter Roberson on 25 Mar If A is a matrix, then max A is a row vector containing the maximum value of each column. To find the maximum over all dimensions of a matrix, use the 'all' option.
