Hi
If I have for loop, and I want increment the value of abc directly to next value in the variable DD...How?

Example:
DD=[1 3 4 8 9 10];

for abc= min(DD(:)) : max(DD(:)) % start from 1 to 10 by one
.. .. ..
.....
...
end

_______

in the above example, it will increase by one from the minimum value to the maximum value, which means:
1 then 2 then 3 then 4 .... then 10

I want to set the incremental is:
1 then 3 then 4 then 8 then 9 then 10



How can I do that please?

You can increment it just by writing a new value to the variable, but as soon
as the next iteration of the loop starts, the variable will be reset to what
would have been the next in progression if you had not changed it.

There is no way to make a change to a loop variable that will "stick". You
will have to do something like

if abc < DD(K); next; end if

If there's a derivable pattern you can use that to either generate the
indices in a while loop or to load an array and use it as the iterator
values; I don't see it otomh from the example given.

Failing in that, either load the specific values in the array or use
logic to CONTINUE for the values to skip or use a SWITCH construct or
IF...ELSEIF... , etc.

DD=[1 3 4 8 9 10];
for abc=DD
disp(abc);
end

for abc = DD
% do stuff
end

When you use this syntax, the FOR loop will iterate over the columns of DD,
assigning each in turn to the variable abc.
