%I want to display numbers such as .0254 in my legend as opposed to 0.2. How do I change that?

%Some of my Script below:

%2-D plot

if ic == 1

%Color and marker code for creating 2-D plots

 Ncm = 6;  scm = ['r-';'g:';'b-';'m:';'c-';'k:']; 
 h = zeros(Ny,1);  st = zeros(Ny,9);

%Plot curves of T(x,y) for various y values

      nfig = nfig+1;  figure(nfig)
      for j = 1:Ny
        h(j) = plot(x,T(:,j),scm(j,:),'LineWidth',2); hold on 
        st(j,:) = sprintf('%5.1f = y',yy(j));
      end 
      title('2-D Temperature Distribution of Long Wooden Beam')
      grid,xlabel('X Values'),ylabel('Temperature (C)')
      legend(h,char(st),'Location','SouthEast')
      end
