how to find unique rows in cell array in matlab. In MATLAB, I would like to generate n pairs of random integers in the range [1, m], where each pair is unique.For uniqueness, I consider the order of the numbers in the pair to be irrelevant such that [3, 10] is equal to [10, 3].Also, each pair should consist of two distinct integers; i.e. If z-score > threshold, go short, close next day If z-score < -threshold go long, close next day If your rows don't contain positive integers, you can still do the problem by converting it to indeces using unique. This MATLAB function constructs valid MATLAB identifiers, N, from input strings, S. 30, Apr 20. Learn more about matlab unique From these etfs 90 unique pairs can be made. Each pair is constructed as a market-neutral spread. 24, Dec 18. I know randperm can give a me random unique numbers, but Im not sure if its possible to use randperm to give unique pairs? Unique can create a vector of the unique elements and also a vector of indeces to reconstruct the original vector based on these values. how to arrange an array elemets to unique pairs?. Learn more about rearrange; Is there a way to remove these repeating rows without using the unique function? [3, 4] is ok but [3, 3] would be rejected.EDIT: Each possible pair should be chosen with equal likelihood. ... That will allow you to find the unique rows from a cell array, which the MATLAB function unique() will not do. Learn more about vector pairs MATLAB Strategy rules: On each day, for each pair, calculate z-score based on 25-day standard deviation. Learn more about rearrange; Subsequence pair from given Array having all unique and all same elements respectively. What is the best way of creating a 10x2 matrix in matlab where each element is a random int between 1-5, and so that there are only unique pairs of elements in this array? The only other way I can think of is using: 21, Nov 18. The reason I can't use the unique function is because when I implement this matlab script in Simulink's Matlab Function block, the matrix must be sorted first before using the unique … All pairs whose xor gives unique prime. how to arrange an array elemets to unique pairs?.
