How can i combined array automatically
显示 更早的评论
a = [100, 125, 150, 175, 200, 225, 250, 275, 300, 325];
for k = 1: numel(a)
Fx{:,:,k} = a(k:numel(a))
end
Tx = [Fx{:,:,1},Fx{:,:,2},Fx{:,:,3},Fx{:,:,4},Fx{:,:,5},Fx{:,:,6},Fx{:,:,7},Fx{:,:,8},Fx{:,:,9},Fx{:,:,10}];
i want to generate Tx automatically without manual input

I have no idea what you mean with "means 2:10 or 3:10 or 3:9 then??"
However if you are interested in taking only some of the sequence, then have a play around with the indexing:
>> tmp = a(:)*ones(1,numel(a));
>> idx = tril(true(numel(a)));
>> N = 2; % change this! 1, 2, 3, 4, 5, etc
>> idx(:,1:N-1) = false;
>> Tx = tmp(idx)
Tx =
125
150
175
