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.

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. 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. C contains the largest elements from each pair of corresponding elements in A and B. The function finds the largest element of a complex vector by taking the element with the largest magnitude. In vector a , the largest elements, at position 2 and 3 , have a magnitude of 6. The max function returns the largest element in output x and the index of that element in output y. Although the elements at index 2 and 3 have the same magnitude, the index of the first occurrence of that value is always returned. Input fi array, specified as a scalar, vector, matrix, or multidimensional array.

Returns a row vector containing a maximum value for each column. Scalar specifying the maximum value in DMObj when it contains vector of data.

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. 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.

Matlab max

In this tutorial, we will discuss how to find the maximum value from an array and its index using the max function in MATLAB. In the case of an array, it will return the value of the maximum value present in that array along with its index. In the case of a matrix, it will return the maximum values from each column of the matrix in the form of a vector containing maximum values present in all the columns. See the below code.

The function finds the largest element of a complex vector by taking the element with the largest magnitude. Bounds Including Missing Values. Toggle Main Navigation. Algorithms When A or B is complex, the max function returns the elements with the largest magnitude. John Doe on 31 Jan Minimum value, returned as a vector, matrix, multidimensional array, or table. How do I find a maximum within a certain range. Choose a web site to get translated content where available and see local events and offers. Search MathWorks. Data Types : fi single double int8 int16 int32 int64 uint8 uint16 uint32 uint All variables must have data types that support the calculation. If A is a scalar, then max A returns A. You have a modified version of this example.

If any element in the operating dimension is missing, then the corresponding element in M is missing. Trial software. Start Hunting! Each element represents a dimension of the input array. Main Content. Select a Web Site Choose a web site to get translated content where available and see local events and offers. Input array, specified as a scalar, vector, matrix, multidimensional array, table, or timetable. If all elements in the operating dimension are missing, then the corresponding elements in minA and maxA are missing. Usage notes and limitations: Index output is not supported for distributed tabular inputs. If you only want to compute the maximum of one matrix, you need something to use as a placeholder for that second matrix. To find the maximum over all dimensions of a matrix, use the 'all' option.
