Reshaping Multiple Matrices

Hi,

I am trying to reshape 1081 column vectors (size 49x1 each) using a for loop.

I know the loop needs to go from i=1 to i=1081. And the reshape command should look something like this;

T1= reshape(T1,7,7)

However I cannot seem to figure the correct loop for this.

The column vectors are named T0, T1, T3, .... , T1079, T1080.

Can anyone help me with this?

Many thanks

thanks Sean. This info was indeed helpful!

However I am having trouble applying a formula to reshape the matrices within the loop. I tried T(i)=reshape(T(i),7,7) within the loop but it is not working. I'm a little fresh to matlab so excuse my ignorance if i am doing something simple wrong!

thanks

For the index, use curly bracket T{i} rather than parentheses.

Also, if you can concatenate all your original vectors into one large array, then you can do the reshape in one fell swoop:

 >> T = rand(1081,49); % Size of all your vectors, concatenated
 >> Tr = reshape(T,[7,7,1081]); % Each slice in 3rd dim is one of your 7x7

thanks cyclist! I will try this out!!
