Creating variables as needed with arrays
显示 更早的评论
Hello,
I was wondering if there is a way to create matlab variables as needed. I have several sets of data that all have the same amount of columns but different amounts of rows. The amount of rows in each is usually several hundred to several thousand, so creating variable names for each row and saving it in its own array would be tedious. I am trying to use this in conjuction with some of the signal processing apps.
Thank you

Can you give a bit more context? Your current question is not clear to me, as you don't need to name rows inside an array.

do you know how many sets of data you will have? and how they are stored?

Here is an example of how you can split rows of a matrix into separate cells of a cell array,
>> data=rand(3,5)
data =
0.9001 0.3900 0.1140 0.0410 0.7867
0.3637 0.9392 0.7835 0.1848 0.8945
0.5390 0.2387 0.0046 0.3383 0.9172
>> rows=num2cell(data,2)
rows =
3×1 cell array
{1×5 double}
{1×5 double}
{1×5 double}
however, I am puzzled as to why you think breaking the rows into their own arrays would help you. Normally, it is best just to grab the rows as you need them by matrix indexing,
row=data(i,:);
