I want to save results of calculation in an emty struct(3*3*2 with fields:cost)named "mymax".

"stwhole" (3*3*2 with field:cost) at the following code is the name of my original struct. in each field of stwhole that is named cost are two values. and I want to multiply them (these two values of each field) to elements of matrix A separately then find the max of them and save it to corresponding fields in struct "mymax". the size of matrix A is 1*9.

 this code doesn't work correctly.
PLEASE HELP ME
if true
 empty_max.cost=[]
mymax=repmat(empty_max,[3,3,2])
for iteration:1:9
for k=1:9
mymax(k).cost=[]
for i=1:3
for j=1:3
for m=1:2
ops=(stwhole(i,j,m).cost).*A(K)
ty=max(ops)
mymax(k).cost=[ty]
end
end
end
end
end

You will need to change also the initialization into

mymax=repmat(empty_max,[3,3,2,9])

and remove the line

mymax(k).cost=[]

A is 1*9 matrix I want to on each iteration one element of A multiply to stwhole(I,j,m) and max of this product save in mymax. then at the next iteration the second lement of A repeat this process and results save in mymax. and these iterations continue up to the end element of A.

Here is how your code will look like:

if true
  empty_max.cost=[]
  mymax=repmat(empty_max,[3,3,2,numel(A)])
  for k=1:numel(A)
    for i=1:3
      for j=1:3
        for m=1:2
          mymax(i,j,m,k).cost=max(stwhole(i,j,m).cost*A(k))
        end
      end
    end
  end
end
