Need Help Forming a Matrix from an Array
显示 更早的评论
so i have an array that is (4051x1), called xvoltage, and I need to form a matrix with this vector only, I want to do something like a sliding window, that the first row are samples 2650:2655, and then the second row world be from 2651:2656 , and so on successively, can someone help me out i'm stuck , it just keeps repeating the same values forming a five by five matrix.
for p=1:5
for q=1:5
xV(p,q)=xvoltage(2650+q);
end
end

" would it have been hard doing this with a for cycle?"
Something like this perhaps (untested):
V = [rows that you want to get];
C = 5; % number of columns
N = numel(V);
M = nan(N,C);
for k = 1:N
M(k,:) = A(V(k)+(0:C-1));
end
