Matrix P has the same data type as v , and it has n! (To be removed) All possible combinations of set of values. It's easy to enumerate all combinations of n things taken k at a time with NCHOOSEK function. It cannot have type int64 or uint64. Description. example. For example, use C = nchoosek (v,k). Then you create the blank cell array with length equal to 64 - that's how many combinations of three letters you are expected to get. For N x N to be scalar, then x would have had to have been N x M = 1 x M -- but in that case the pdist2() would return 0 making it essentially useless to make the pdist2() call. In this case, x must be a nonnegative integer. To update your code, change instances of the function name combnk to nchoosek.

Use the nchoosek function instead. Syntax. Each row of P contains a different permutation of the n elements in v . Now, the objective function return value for fminsearch needs to be a scalar. Use the nchoosek function instead. n and k must be nonnegative integers. Normally there should be an index for each subset but since they are all the same length, the number of unique combinations will be the same so you can just reuse 4x the same index. If you want it symbolically you can use something like: syms x f = x + sin (x); g = x - sin (x); equ = simplify (f*g); Share. To update your code, replace instances of the combntns function with the nchoosek function.
