Filling in multidimensional array efficiently

I need to fill in array of the size (900,1800,80,60) --> (tr,t,f,ch) through a for loop. In every iteration, I will get a bunch of data for a particular f and ch. This bunch, call it b, is the size of 50 by1800 and sometimes it is 49 by 1800.
Example:
array(?,:,f_1,ch_1) = b
I wish in each loop to fill in bunch b in my array. Is there an easy way to determine "?" in each loop? Alternatively, is there an easier way to fill in "array"?

Something like this maybe?
k = 1;
% your loop
b = r x 1800 matrix
f = whatever
ch = whatever
r = size(b,1);
array(k:k+r-1,:,f,ch) = b;
k = k + r;
% end loop
But it is not clear how f and ch change within the loop, so this might not work as written.
