what is deferent between Matlab2013a "ones" function with Matlab2013b

dear all, i used a code in matlab2013a and it get answer to me, the code is :

M=xlsread('pars.xlsx','par10');
out10=cell2mat(arrayfun(@(x,y) x*ones(y,1),M10(:,1),M10(:,2),'un',0))

, But now i change my matlab to 2013b and the code doesnt work , the error is:

Error using ones
Size inputs must be integers.

Error in @(x,y)x*ones(y,1)

what is wrong with it? thanks

Hi,

you use x and y as function parameters, so they can have non-integer values. But ones() creates a matrix, which needs to have integer values as dimensions.
