A=[20 40 60 80 100]
B= [ 120 140 160 180 200]
for t=1:length(A)
for r=1:length(B)
G=rand(A(t),B(r))
end
end
If i run the code it executes and I can see only (100x200) matrix in the workspace. Could anyone tell me how to view all sizes (20x120),(20,140),(20,160)...... in the workspace.

You permanently overwrite G in the above loop.
Only rand(A(5),B(5)) remains at last for G which is 100x200.
If you want to have matrices of sizes (20x120),(20x140) etc. in one structure, create G as cell(5).
Best wishes

Probably the easiest way is to create ‘G’ as a cell array:
G{t,r} = rand(A(t),B(r));
Then you can address each element of the cell array to get the corresponding matrix to use later in your code.

If I use the command it gives me the size of the cell array. But how to get the data of each matrix with respect to rand command.

Address the cell array with the appropriate subscripts to get the data in it:
UseMatrix = G{2,3};
will load the matrix in ‘G{2,3}’ into the ‘UseMatrix’ variable.
You can use the matrices in the cell array directly in your calculations. You do not have to load them to a separate variable first. (I am doing this here simply to demonstrate the idea.)
