# combinations of a vector matlab

Thank you. This MATLAB function returns a matrix containing all possible combinations of the elements of vector v taken k at a time. There are no restrictions on combining inputs of different types for combnk(v,k).Alternative Functionality MATLAB ® contains the function nchoosek, which can also return all combinations of an element vector and has extended functionality using MATLAB Coder . I'm working on the classification of bridge damages. The problem is that I don't know the number of vectors for which I need to calculate the combinations. If my math is correct there should be 64 combinations. Description combos = combntns(set,subset) returns a matrix whose rows are the various combinations that can be taken of the elements of the vector … This is the number of combinations of things taken at a time. k can be any numeric type, but must be real. Is there a way to select all possible combinations of column vectors from a matrix in MATLAB ? He wanted to take every combination of one value from each of three distinct vectors. Let's say A is a binary matrix of 1's and 0's and i had the cases … MATLAB Mathematics Elementary Math Discrete Math nchoosek On this page Syntax Description Examples Binomial Coefficient, "5 Choose 4" All Combinations of Five Numbers Taken Four at a Time All Combinations of Three n I want a way to store all 31 of these combinations in an array, for example a cell array, with n cells, within each is an array in which each row is a vector combination of the elements. C = nchoosek(v,k), where v is a row vector of length n, creates a matrix whose rows consist of all possible combinations of the elements of v taken at a time. MATLAB: How to find all the combinations of a vector elements whose sum is equal to a given number vectors Hi all, I' ve got this vector made of 24 elements: P = … I want to create all combinations of a 1x6 vector, composed only of 1's and 0's. This MATLAB function returns a matrix containing all possible combinations of the elements of vector v taken k at a time. All possible combinations of set of values, This MATLAB function returns a matrix whose rows are the various combinations that can be taken of the elements of the vector set of length subset. Number of elements to select, specified as a nonnegative integer scalar. Question 4 answers Asked 9th Jan, 2019 Khushboo Verma I … There are no restrictions on combining inputs of different types for combnk(v,k).Alternative Functionality MATLAB ® contains the function nchoosek, which can also return all combinations of an element vector and has extended functionality using MATLAB Coder . Now, this could be done easily with some nested for loops, but that really does violate the spirit in which such challenges are issued. I did For example, if there are two -1's in the first half, they can be placed in 4 choose 2 = 6 ways, and for each of them there will be 6 ways to place the two 1's in the second half. MATLAB Mathematics Elementary Math Discrete Math nchoosek On this page Syntax Description Examples Binomial Coefficient, "5 Choose 4" All Combinations of Five Numbers Taken Four at a Time All Combinations of Three n for a linear system equation of Ax = B with A dimensions 5x5 and x, a column vector. I have a vector s =[0,0,0,0,0,0,0,0,0] for which i wish to find out all possible combinations and also generate all possbile vectors for. Number of elements to select, specified as a nonnegative integer scalar. Number of elements to select, specified as a nonnegative integer scalar. MATLAB: Combinations of values of array of vectors (of different lengths) but ONLY in order the vectors appear in the array combination recursion Hi, I'm trying to transcribe protein letters to DNA codons. This MATLAB function returns a matrix whose rows are the various combinations that can be taken of the elements of the vector set of length subset. This MATLAB function takes any number of inputs, Matrix of N1 (column) vectors Matrix of N2 (column) vectors You clicked a link that corresponds to this MATLAB command: Run the command by entering it in the MATLAB My colleague walked into my office with a MATLAB question, a regular pasttime for us here at the MathWorks. e.g. I want to fill a vector with specifice numbers of 1's and -1's, and the rest are zeros. Starting with all zeros and ending with all ones. It should be done in linear combinations. Number of elements to select, specified as a nonnegative integer scalar. k can be any numeric type, but must be real. There might be 3 as in this case, or there may be 10, and I need a generalization. k can be any numeric type, but must be real. The damage is expressed with a qualitative number ranging from 1 to 5 (the first vector) CR=1:5, the other vector is the position of damage on the bridge ranging also it from 1 to 5 (a fifth of the length per time). at k = 4 : Description combos = combntns(set,subset) returns a matrix whose rows are the various combinations that can be taken of the elements of the vector … The groups can vary in size (number of elements), but all elements have to been included in the groups. For Matlab 7.8, this is about 30% Matrix C I want to generate every possible combination of elements in a vector. Can you please help me to this in MATLAB This MATLAB function returns a matrix whose rows are the various combinations that can be taken of the elements of the vector set of length subset. k can be any numeric type, but must be real.
