For cycle over a struct array

Hello everyone,

I am considering a 1x1 struct array ( named hs) that contains 49 matrices ( 72x77) that represent the significant wave height in all the grid points of my domain. I would like to create a for cycle to plot how the significant wave height is changing during time/space. I know how to extract the matrices one by one from the struct array but it is time consuming and I would like to create a cycle ( with the pcolor command).

Xp (72x77) is the matrix that contains the x-coord of the grid points

Yp (72x77) is the matrix that contains the y-coord of the grid points

How can i write the for loop?

Thank you for your help.

"I know how to extract the matrices one by one from the struct array"

Can you show how you do this? I ask because the situation is a little confusing to me. For example, "a 1x1 struct array" is a scalar struct. If it "contains 49 matrices", does that mean the struct has 49 fields, with each field being one matrix? Probably seeing the code you have so far would help to answer those kinds of questions.

Thank you for your answer! This is the content of 1x1 struct array..

I can extract a matrix in this way : hs1=hs.Hsig_20000103_000000(:,:);

But I am not able to create a for cycle like this ( of course what I wrote below doesn't work.. it is just to show what I kind of want to obtain).

for i=1:49

pcolor( Xp,Yp,hs(i))

end

s = struct2cell(hs) ; 
N = length(s) ;
for i = 1:N
    pcolor(XP,Yp,s{i})
    drawnow
end

It works fine! Thank you
