I am able to edit the values of different variables of class cell, double etc. but am unable to edit the value of a variable of class dataset using the variable editor.
load fisheriris
NumObs = size(meas,1);
NameObs = strcat({'Obs'},num2str((1:NumObs)','%d'));
iris = dataset({nominal(species),'species'},...
{meas,'SL','SW','PL','PW'},...
'ObsNames',NameObs);
openvar('iris');

It is not possible to edit a value of a variable of class dataset using the variable editor in MATLAB 7.6 (R2008a).
As a workaround, update the values of the variable using the command line, for example:
iris(1,2) = dataset(4.5);
