This error means that you are trying to assign to an element of vector blob (size 1x1) a vector a size 1x9. That happens because in MATLAB, a string is a vector of characters: 'rectangle' is a vector of size 1x9, but blob(i) has size 1x1.

Are you trying to store strings of various sizes in the variable blob? What do you want to do when storing strings in a vector?

yes i am trying to store various sizes of string in blob array

In that case, you should use a cell array . Cell arrays can store different sizes and types of data. They are more flexible that the traditional array.

Cell arrays are used very similarly to regular arrays. The difference is in how you access data: with curvy brackets {} instead of [] and ().

In your code, I would simply replace blob(i) by blob{i}.

but i get this error

Cell contents assignment to a non-cell array object.

Error in connect (line 68) blob{i}='Rectangle';

Do you use blob somewhere else? Do you mind showing your code where you use blob?
