Populate Cells of Structure Array with Empty Tables

Hello,

I want to have a Structure Array with 1 x C structure array with N x 10 tables.

Since the total number of columns in the Structure Array varies with the imported data, I'm not sure how to accomplish this.

The first thing I did was make a zero-filled N x 10 table, with which I want to use to populate each cell of the Structure Array.

I wanted to do something like this next:

Table = zeros(N,10)

for i=1:C
    Struc_Array.a(i) = Table
end

So essentially, this For Loop is used to A. Create the Structure Array to the appropriate size, and B. Fill each cell with the zero Table.

Would it be something like this instead (after reading this post --> I haven't tried it yet):

Table = zeros(N,10)

for i=1:C
    Struc_Array(i).a = Table
end

Perhaps my main issue is with how Structure Arrays work and their syntax.

I watched this video, as well as look over many pages and forum posts about the topic.

Thanks.

This might be what you want:

N=3; C=4;

T = array2table(zeros(N,10));

[Struc_Array(1:C).a]=deal(T);
Struc_Array.a
