Delete elements in a array
显示 更早的评论
Hi, I have a large array. I want to delete certain elements in the array. I want to delete the 390th element, and then after that every 391th element......
So need to delete 390, 781, 1182 etc..........

So when you say "array", you mean a 1-D vector?
X = randn(49121,1);
indices = 390:391:length(X);
X(indices) = [];
length(X)

X = randn(100,100);
% not sure how far you want the vector to go
indices = 390:391:1e4;
X(indices) = [];
Then you'll need to reshape X into an array. Or you can just replace the elements with NaNs
X = randn(100,100);
% not sure how far you want the vector to go
X(indices) = NaN;

Yes. 48996 to be precise, just like it does give you in the 1D version above.
