Hi community,
I want to convert an equation like: N=1-X into an character array like: Z='N=1-X' or the other way around. The problem is functions like string2num() do not accept variables as input.

Again, as Matt asked, what form does the equation takes in your code? There are many ways to code an equation for plotting and the answer is going to depend on how you've done it.

methods(Static) function surfplot(handles,X,Y,fun) %<---change s=surf(X,Y,fun(X,Y)); s.FaceColor='interp'; a=gca; a.Box='on'; zlim([0 1]); xlabel('x') ylabel('y') % I want to display the function instead of N %
N=strrep( func2str(fun) ,'@(x,y)','' ); %<---change zlabel( N ) % I want to show the function N on the static text field% set(handles.text,'string', N) end
function Node1plot(handles,X,Y)
fun=@(x,y) 1/4*(1-x).*(1-y); %<---change
figure('Name','Plot Formfunctions: Node1plot',... 'NumberTitle','off', 'Units', 'Normalized', ... 'OuterPosition', [0.5 0 0.5 1]); colormap(jet) Formfunktionen.surfplot(handles,X,Y,fun) %<---change end
end
