I have this example:
for t=20:10:30
for i=900
a=t+i
end
end
I want result to be (Vector a):
a=
920
930

Ran in:
t = 20:10:30;
i = 900;
a = t.' + i
a = 2×1
920 930

Ran in:
Or, if you must use loops:
t_all = 20:10:30;
i_all = 900;
nt = numel(t_all);
ni = numel(i_all);
a = zeros(nt*ni,1);
idx = 1;
for t = t_all
for i = i_all
a(idx) = t+i;
idx = idx+1;
end
end
disp(a)
920 930
Or:
t = 20:10:30;
i = 900;
nt = numel(t);
ni = numel(i);
a = zeros(nt*ni,1);
idx = 1;
for t_idx = 1:nt
for i_idx = 1:ni
a(idx) = t(t_idx)+i(i_idx);
idx = idx+1;
end
end
disp(a)
920 930
Or:
t = 20:10:30;
i = 900;
nt = numel(t);
ni = numel(i);
a = zeros(nt*ni,1);
for t_idx = 1:nt
for i_idx = 1:ni
a((t_idx-1)*ni+i_idx) = t(t_idx)+i(i_idx);
end
end
disp(a)
