How to save inner loop data with outer loop data in one matfile
显示 更早的评论
Hello Matlabers!
So basically i have this code
for i=1:5
r=5;
W = rand(m,r);
H = rand(r,n);
for rank=2:2:20 % Now for every value of rank I want to compute W0 and H0
W0 = rand(m,rank);
H0 = rand(rank,n);
end
% finally in the end I want to save all values. For each iteration of the OUTER loop,
% I will have all values of the INNER loop as well.
save( ['DATA/data_',int2str(i),'.mat'],'W','H','W0','H0','-v7.3' )
end
So i wish to have my matfile contain files like
Data_1
W,H
W0_2,W0_4,W0_6,...,W0_20
Data_2
W,H
W0_2,W0_4,W0_6,...,W0_20
.
.
Data_5
W,H
W0_2,W0_4,W0_6,...,W0_20

"W0_2,W0_4,W0_6,...,W0_20"
Avoid creating variables with dynamic variable names:
It is much simpler and much more efficient to use indexing.

Using a structure (or any other array) is better than using dynamically named variables:
m = 2;
n = 3;
r = 5;
V = 2:2:20;
for ii = 1:5
W = rand(m,r);
H = rand(r,n);
S = struct();
for jj = 1:numel(V)
S(jj).W0 = rand(m,V(jj));
S(jj).H0 = rand(V(jj),n);
end
F = fullfile('DATA',sprintf('data_%d.mat',ii));
save(F,'W','H','S','V')
end

m = 2;
n = 3;
r = 5;

for ii = 1:5
W = rand(m,r);
H = rand(r,n);
W0 = cell(1,numel(V));
H0 = cell(1,numel(V));
for jj = 1:numel(V)
W0{jj} = rand(m,V(jj));
H0{jj} = rand(V(jj),n);
end
F = fullfile('DATA',sprintf('data_%d.mat',ii));
save(F,'W','H','W0','H0','V')
end
