From: Dave on 18 Jul 2010 13:56 Dear Matlab Gurus, Is there an easier way to assign a vector to a vector element? I currently have to pre-declare a matrix e.g. A=zeros(10,3); A(:,1)=data(:); when really I would simply like to do A(1)=data; where data is a vector of values

In an array or matrix, A(1) refers to only a single element; can't be interpreted as anything else or it would break any reference in looping constructs, etc., etc., etc., ... To somehow have some other sort of non-orthogonal interpretation in assignment statements only would be _a_bad_thing_ (tm) from that standpoint only even if could figure out a non-ambiguous set of syntax rules. -- --
