Hi,
I am new to MATLAB and currently am dealing with a struct with three columns (Area,Centroid and BoundingBox).
There are 14 instances in total. The Centroid column consists of data which are comma seperated like [102.92,429.33]. I have to convert this column in to a 14x2 matrix.
I tried
matr = {comp.Centroid}';
but it returned a 14x1 cell.
Kindly help me regarding the issue.
Thanks

Thanks a lot Ameer Hamza. I was not expecting a one line answer. I was thinking that i will need a nested loop for the problem. Thanks a lot once again.

I am glad to be of help! MATLAB is well-known for its vectorized operations, and loops can be avoided in most situations. For example, even with your line of code, you can get the same output by using cell2mat
