dec2b_man.m

My code is attached below and it has the "Subscripted assignment dimension mismatch." error

How can I fix this? and how can I store my data into a 2D array? Thanks!

Hi. The output of dec2bin is a char not a double. So you should define "out" as a cell:

 [m,n] = size(x);
 out = cell(m,n);
 for i = 1:m
     for j = 1:n
         out{m,n} = dec2bin(abs(x(m,n)));
     end
 end

Cheers! Renato

Hi Renato,

I tried doing your suggestion in defining 'out' as a cell and ran the program but then the output shown only brackets and 1 dec2bin conversion at the last element of the array

sorry, it should be:

out{i,j} = dec2bin(abs(x(i,j)));

Hi Andrei,

I tried doing your suggestion but this error occurred: "Error using cellstr Too many input arguments."

How do you suggest to go about this?
