How can I create a structure?

Hello all,
I am trying to create a structure in which I want to store some information. For eg, I found number of columns and rows of an RGB image but whenever I am storing it in a structure its just giving me the name of that particular file not the actual value. Below is the code I used:
imRGB=imread('filename.jpeg');
Columns=size(imRGB,1)
P(2).Columns='Columns'
Rows=size(imRGB,2)
P(3).Rows='Rows'

Note that this is incorrect:
Columns=size(imRGB,1)
The first dimension of all arrays are the rows.
As well as that, note that you are creating a non-scalar structure. The unallocated fields of all elements of that structure will simply contain empty arrays, i.e.:
P(1).Columns
P(1).Rows
P(2).Rows
P(3).Columns

Remove the quotation marks. You're storing the string 'Columns' and 'Rows' isntead of the actual numeric variable.
You also dont need the indexing for your structure P.
P.Columns = Columns;
P.Rows = Rows;
should suffice
