先选择Xnew_ks_notsel_ks_sel,然后选择Select from array,再选idx_validation,再点击Invert就会反向选择,意思就是把Xnew_ks_notsel_ks_sel剩下的数据全选上。 To choose the samples of prediction, select the matrix Xnew_ks_notsel_ks_sel again in the “Data matrices in the workspace” group. Use ...

function because I don't want all possibilities to have the same probability of being selected. So what I have done is created a row vector , (x), of all the possible card values. Now I would like draw a random number from this selection for my 'draw' function. Thanks for the help...
You can use therandpermfunction to create adoublearray of random integer values that have no repeated values. For example, create a 1-by-5 array containing integers randomly selected from the range [1, 15]. r4 = randperm(15,5);
