X.coords = something?

Question

1 个投票

Hi,

I am trying to understand a code.. the following equation is in it:

y.coords{t} =(sorted_eig_vect(:,1:dimension(t)).*(ones(N,1)... *sqrt(sorted_eig_val(1:dimension(t)))'))';

what does the y.coords do exactly? This may be pretty basic but I really don't know the *.coords thing. Any help or insight to this would be great.

Thanks - K

This creates a field in the structure y. This field is a cell array. Look at this:

Y.myfield = 2;
Y.yourfield = 3;
Y  % Show the structure Y.
Y.ourfield{1} = magic(3);
Y.ourfield{2} = magic(4);
Y  % Show the structure Y.

Now to access the values stored in the fields of the structure Y, use structure addressing:

R = Y.myfield
S = Y.yourfield
T = Y.ourfield{2}

For more information, search the documentation for structures. You could start here:
