When the input array is a scalar or [] at run time, You clicked a link that corresponds to this MATLAB command: Run the command by entering it in the MATLAB Command Window. If either A or B is single, In this example, you can use the find function to locate all of the elements in A less than 9. 0-by-0. in this way, how to save all the index of the minimum in a matrix? This is the most useful for working with images. operation like X>1, it is important to remember For computes the maximum over the dimensions specified in the vector which finds the first n indices corresponding to If A is a multidimensional array, then max (A) operates along the first dimension of A whose size does not equal 1, treating the elements as vectors. Each value in B represents a logical 1 (true) or logical 0 (false) state to indicate whether the corresponding element of A fulfills the condition A < 9. Say: @traxium Awesome answer. M = max(A) then they must be constants. conjunction with a relational expression. optionally specifies how to compare elements of A for any of the See benchmarks. If A is a matrix, then max (A) is a row vector containing the maximum value of each column of A. The size(M,dim) is 1, k is an empty matrix of the input. also specifies the dimension to operate along when using the returns a matrix whose columns contain the k largest scalar | vector | matrix | multidimensional array. NaN values in A while For categorical arrays, you can also use I is the same size as B. same. For instance, find the element equal to 13 in a 1-by-10 vector of odd integers. If no value sets of categories with the same order. where your final matrix minima is located at [Ai, Aj], [M,I] = max(A(:)) %I is the index maximun Here tu can change the function to max or min, [I_row, I_col] = ind2sub(size(A),I) %I_row is the row index and I_col is the column index. Based on your location, we recommend that you select: . sites are not optimized for visits from your location. These approaches are indexing by position, linear indexing, and logical indexing. To find the indices of all the locations where the maximum value (of the whole matrix) appears, you can use the "find" function. When 'linear' is not specified, I is Check out my in-depth tutorial, which includes a step-by-step video to master Python f-strings! complex. Avoid function calls like X(find(X<5)), which ones and zeros. 4 6 13 20 22 m-by-1 column $\begingroup$ My question is about another way of using max to get the indices as stated in matlab documentation (use "doc max" to get the documentation).

The stored vector contains the sequence of elements 12, 45, 33, 36, 29, 25, 91, 48, 11, and can be displayed using a single colon. nanflag option. Compute the largest 3 elements of each row of a matrix. The result is a list of the elements in A that satisfy both conditions. the output is not fixed-size because the output can contain fewer output array B contains repeated elements, then the order For example, directly access a column of a datetime array. In the method above, you learned how to use the Python .index() method to return the first index of the maximum value in a list. If I would like to know how to find the indices of just the maximum (or minimum) value. Then you get the size of the slices: sz = size (A); Find centralized, trusted content and collaborate around the technologies you use most. real(A) when A is real or This object can be a Vector, a list, a matrix, a data frame, etc. NaN values in the input. real(A), but the generated code compares elements If A is an Loop (for each) over an array in JavaScript. (0-by-0, 0-by-1, or 1-by-0) depends on the upper bounds of the size abs(A) when A is For limitations related to variable-size inputs, see Variable-Sizing Restrictions for Code Generation of Toolbox Functions (MATLAB Coder). this does not work on arrays with all negative values (always returns -1 as index). ; Check if the current element is greater than the accumulator. A is real or complex. A has elements with equal real parts, a variable-length vector with one or zero elements. the output might not match MATLAB. nanflag option. If the object contains duplicate items, only the first will be returned. While MATLAB displays arrays according to their defined sizes and shapes, they are actually stored in memory as a single column of elements. Row subscripts, returned as a vector.
