i did some calculation and got a variable 'binr' with 1 row and many column values( more than 800)....
i wanted to save it in a matfile in a format, so that i can contain values only upto 25 coulmns in one row.... so i wrote the code as
binr = reshape(binr,25,[]).';
but if binr is not divisible by 25 i'm getting error as
??? Error using ==> reshape
Product of known dimensions, 25, not divisible into total number of elements, 871.
Error in ==> Todel at 176
binr = reshape(binr,25,[]).';
What can i do to store the value of this variable in a matfile with only 25 columns even if the value in binr is not divisible by 25..... is it possible.... please do reply....

Do you want to throw away the extras, or do you want to pad to make up a full line ?

dont throw away extras sir....
it should have minimum 25 rows 25 columns..... if more than that only 25 columns but any number of rows..... if less than 25 rows 25 columns add some pattern.....
is it possible to add a pattern like "0 0 1 1 0 0" or " 1 1 1 0 0" or some pattern....to fill the remaining rows and columns..... but how to do that sir.....
please do reply sir......

fillpat = repmat([0 0 1 1], 1, 6]);
binr = reshape( [binr, fillpat(1 : mod(-length(binr),25))], 25, []) .';

binr( end+1 : 25, :) = repmat( [fillpat, 0], max(0, 25 - size(binr,1)), 1);
