C = max(A,B,nanflag) How can I remove a specific item from an array in JavaScript? When the input array is a scalar or [] at run time, X. elements in X using find(X,n,'last'). This approach lets you specify the last column without knowing exactly how many columns are in A. scalar. elements along the first dimension whose size does not equal 1. Do you want to open this example with your edits? 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. If A is a vector, then maxk . The task of this reduction function is to somehow combine or reduce two values into a single value, and to return that reduced value. If A has type categorical, then it How can I find the maximum value and its index in array in MATLAB? elements in X. I have stored in a logical array the extreme values (the pink) indicated by TRUE and all the others (the blue) indicated by FALSE. an integer data type with the other a scalar double, Even when you provide the output vector k, returns the linear index into A that corresponds to the [M,I] = https://jsben.ch/wkd4c. One of the benefits of these arrays is that they come with many built-in functions and methods that normal lists do not. In the next section, youll learn how to return the index of the maximum value if no duplicates exist or you only need the first item. Thus, linear indexing numbers the elements Attention: It doesn't deal with multiple maximums! I is the same size as the first output. To complete the work of @VFDan, I benchmarked the 3 methods: the accepted one (custom loop), reduce, and find(max(arr)) on an array of 10000 floats. The Python enumerate() function is an incredible function that lets us iterate over an iterable item, such as a list, and access both the index and the item. If you only want to compute the maximum of one matrix, you need something to use as a placeholder for that second matrix. % Function: Calculate the minimum value and its indices in a multidimensional array. While linear indexing can be less intuitive visually, it can be powerful for performing certain computations that are not dependent on the size or shape of the array. Next, replace all values in A that are not equal to 10 with a NaN value. The magenta points are the extreme points. more information, see Run MATLAB Functions in Thread-Based Environment.
