Thread-Based Environment Run code in the background using MATLAB® backgroundPool or accelerate code with Parallel Computing Toolbox™ ThreadPool . A = [3 5 NaN 9 0 NaN]; M = cummax (A) M = 1×6 3 5 5 9 9 9. B = cumsum (A) returns the cumulative sum of A starting at the beginning of the first array dimension in A whose size does not equal 1. categorical is a data type that assigns values to a finite set of discrete categories, such as High, Med, and Low.These categories can have a mathematical ordering that you specify, such as High > Med > Low, but it is not required.A categorical array provides efficient storage and convenient manipulation of nonnumeric data, while also maintaining meaningful names for the values. The question is to write a function to reverse a vector so v= [1 2 3] becomes v= [3 2 1] It must be recursive. To put it simply have a 2d-Lookup table a basically want to reverse engineer it. The inverse of a matrix does not always exist. B = fliplr(A) returns A with its columns flipped in the left-right direction (that is, about a vertical axis).If A is a row vector, then fliplr(A) returns a vector of the same length with the order of its elements reversed. A row vector happens to be a matrix, but so does a column vector, and two or more dimensional matrices. Copy to Clipboard.
