how to create cell array for time format elements in matlab
显示 更早的评论
Hi all, I want to create a cell array and increasing the rows at each loop, while the elements of my cell array are all in time format , for example 02:34:12.
Following is my code.
uuniq=unique(rad_index);
for i=1:length(uniq)
for j=1:length(rad_index)
if uniq(i)==rad_index(j)
dis(j,:)= diff(j,:);
end
end
MyArray{i}=dis;
end
where value of dis at i=1 and end of second loop will be:
dis=
00:02:11
00:03:47
00:03:46
now I want to create a cell array which keep these information as the first row and increase the row when i=2, i=3, .... I was thinking MyArray in above code should give me what I want but actually gives me the following error:
Cell contents assignment to a non-cell array object.
any idea is appreciated ...

Your error message means that you are indexing the cell-array to get a subset of its elements as another cell-array.
i.e.
>> y = {1,2,3};
>> z = y(2); class(z) %z is a cell-array of 1 element
>> z = y{2}; class(z) %z is a double
so you want to change your code to use '{}' braces to access the underlying element, and use '()' paranthesis to access sub-cell-array.

>> z = {1,2,3}
z =
[1] [2] [3]
>> z{1}
ans =

>> z{1} = z
z =
{1x3 cell} [2] [3]
>> z{1}{1}
ans =
1
>> z{1}{2}
ans =
