Hi guys,

After extracting some data the result is something like this:

h=[ 2 3 4, 5 6 , 7 8 9]

which is wrong and therefore an error appears because the matrix has to be square.

My question is, how can i fullfill the empty spaces in h with NaN.

Can anyone help?

Thanks in advance!

Inês

How your data are stored?

One possible solution is to use padcat function from file exchange.

 a = [2 3 4]:
 b = [5 6];
 c = [7 8 9];
 h = padcat(a,b,c)

And your h will be

h = [2 3 4; 5 6 NaN; 7 8 9]

yes i know that.... but i want a general solution like with a cycle in which i don´t have to manually put NaN in every single gap...

As Azzi mentioned, it would be difficult for us to look for a general solution unless we look at how your data were stored.
