Hi

I will appreciate your support on this:

I have a 3 x 9 matrix f with some finite and non-finite values. I have to manipulate f so that I will have only finite values (that is easy), and each row will have Ns finite values (as shown in temp). N is apparently divisible by Ns. Essentially, if the finite number of values in a row(s) of f is greater than Ns, they have to be adjusted amongst the other rows.

N=9; Ns=3;

f=[1,2,6,7,8,nan,nan,nan,nan;3,4,nan,nan,nan,nan,nan,nan,nan;5,9,nan,nan,nan,nan,nan,nan,nan];

temp=[1 2 6 ; 3 4 7 ; 5 9 8 ];

It could be simple, but I am now able to come up with an elegant solution. Any suggestion on how to do this?

Thank you

在 MATLAB Online 中打开

f =[1,2,6,7,8,nan,nan,nan,nan;
    3,4,nan,nan,nan,nan,nan,nan,nan;
    5,9,nan,nan,nan,nan,nan,nan,nan];
out = nan(size(f,1),Ns);
d = f(~isnan(f));
try 
   out(1:numel(d)) = d; 
catch 
   msg = lasterror.message 
end
