save for loop variable in workspace
显示 更早的评论
Hello.
I am new to coding and have a question.
I'm running a script which gives produces many variables in the output inclduing a 1x1 structure with 6 fields, I want to save one of the fields: "PM.res" each time. I'm using loop numbers:
loop = 1
at the beginning and
loop = loop + 1
in the for loop so I will incorporate this when saving but I want to know how. I want to save each one as a variable in the workspace, so it can be used within the rest of the for loop.
Thank you.

Given that you are apparently incrementing your own loop counter then presumably you have a WHILE loop.
In that case, try this:
C = {};
loop = 1;
while ..
.. your code here
C{end+1} = PM.res;
loop = loop+1;
end
If the total number of iterations is known in advance then a FOR loop would be simpler and more efficient.

"...but I included the counter to keep track of which part of the data the for loop is at."
FOR loops already have a "counter", in most cases there is no need to duplicate that information with your own separately-defined "counter" as well. Therefore you can write simpler and more efficient code:
N = 720;
C = cell(1,N);
for k = 1:N
..
C{k} = PM.res;
end
