how to increase matrix size
显示 更早的评论
for example i have matrix size 5x3, i want to increase size of matrix became 10x3.
example my data :
A = [997.400000000000 -1.10000000000000 70.4000000000000
997.500000000000 -1 70
997.600000000000 -1.50000000000000 72
997.700000000000 -1.80000000000000 73.2000000000000
997.800000000000 -1.80000000000000 73.6000000000000]
I want to my data like this :
A = [997.400000000000 -1.10000000000000 70.4000000000000
NaN NaN NaN
997.500000000000 -1 70
NaN NaN NaN
997.600000000000 -1.50000000000000 72
NaN NaN NaN
997.700000000000 -1.80000000000000 73.2000000000000
NaN NaN NaN
997.800000000000 -1.80000000000000 73.6000000000000

s = size(A);
P = cat(3,A,nan(s));
out = reshape(permute(P,[2 3 1]),s(2),[]).';
or
out = nan(size(A).*[2 1]);
out(1:2:end,:) = A;
