Hi,

I want to assign some matrices to 1 matrix that can be represent 6 matrices.

for example for 3 matrices: f1=[100 0 100]; f2=[500 100 0]; f3=[0 300 300]; f=[? ? ?]

What can I do?????

I got stuck for 2 month, please help.

thanks.

You definitely shouldn't be stuck for 2 months on something like this! If you state a problem clearly enough as you did here you should get an answer within a few hours on this site in general so don't just stay stuck for that long, though obviously do try things yourself first.

Are all your matrices the same size - i.e. 1-by-3?

If so then

f = [f1; f2; f3;...; fn];

will work to give you an n-by-3 matrix where each row is one of your fn.

Ideally you don't want to have variables named as f1, f2, f3, etc in the first place though so if possible put the data into this single matrix format straight away without the need to combine multiple variables like this.

How do you want it to combine f1, f2, etc in that case?

If they are all 1-by-3 and you want f to be a 1-by-3 combination of them then you will need to either sum then, average them or some other mathematical operation to combine n results into 1 result of the same size.
