Scalar structure required for this assignment - For Loop
显示 更早的评论
Hi, I was looking at this example below, and was wondering if it was possible to solve the error while keeping the for loop.
myStruct=repmat(struct('text1',0),10,1);
myarray = [
1 2 3 4 5 6 7 8 9 10];
for j = 1:10 mystruct(j).text11 = myarray(j); end
mystruct.text11 = myarray

The for loop indexes to do the assignment, and that works.
But the next line after the for loop... what is the intention of that? Are you trying to find a non-loop way to accomplish what the loop does?

"I was looking at this example below, and was wondering if it was possible to solve the error while keeping the for loop"
The for loop gives two working approaches for assigning to a structure array: a FOR loop and a comma-separated list.
Why do you think that the FOR loop does not work?

For some reason I'm getting errors when I try to comment below your comment Walter.
When I try running that code it gives out this output.
Scalar structure required for this assignment
I think the original poster of the question wanted to have 10x1 struct with first field being ten 0s and second being 1-10. The poster solved it by turning myarray into cells straight, but I was wondering how to use for loop to solve it.
"I think the original poster of the question wanted to have 10x1 struct with first field being ten 0s and second being 1-10."
Correct.
"The poster solved it by turning myarray into cells straight..."
... and also by using a loop, which is included in their post.
The line of code which causes the error is totally unrelated to the loop.
"...but I was wondering how to use for loop to solve it."
They already showed such a loop. Why not try the loop that they already showed?
Perhaps you are getting confused by the line of code which throws an error (and is rather the point of that post), but which is not part of the loop. Here is their code with the one unrelated following line of code removed, the variable names corrected, and using standard alignment:
mystruct = repmat(struct('text1',0),10,1);
myarray = 1:10;
for j = 1:10
mystruct(j).text11 = myarray(j);
end
Checking:
mystruct
mystruct.text1
mystruct.text11
So far everything seems to be working as expected.
