How to I combine matrix?

Hey there, i just started to work on matrices in matlab and i had a problem with that. Problem is

fet is a function. it takes 1 and 2 variables in for loop. When fet() take 1 it make it 1x10 sized matrices. When fet() takes 2 it make it 1x10 sized matrices also.

I want to make variable named "write" is equal to 1x20 sized matrices after for loop.

for i=1:2
 write=fet(i)
end

Instead, do it in the loop while you can.

for i=1:2
 write(i,:)=fet(i)
end

When I did this, function returns me 2x10. But I want 1x20.

Then add the following line after the loop:

write=reshape(write.',1,[])

thank you!

Also, When fet() take 1 it make it 1x10 sized matrices. When fet() takes 2 it make it 1x30 sized matrices also.

I want to make variable named "write" is equal to 1x40(1x10 + 1x30) sized matrices after for loop.

how can I do it?

For different sized vectors, you need to use cell arrays. Change your code to this:

for i=1:2
 write{i,:}=fet(i)
end
write=cell2mat(reshape(write.',1,[]))

this code gives the following error.--Cell contents assignment to a non-cell array object.-

1x10 1x30 the bottom line is not written

[Birdman]

No, of course clean up your variable before you do it and then run the code.

Okey i understand ,thank you very much!
