Hello,

I'm trying to create a surfplot with sliders that will update the input values of the system.

The values for the X and Y axis remain constant but a certain parameter is changed to change the outcome in the Z domain. I have used

TEST_function(PARAM_1); %This calculates X_vector, Y_vector and Z_array
f = figure;
ax = axes('Parent',f,'position',[0.13 0.39  0.77 0.54]);
h = surf(X_vector,Y_vector,Z_array);
b = uicontrol('Parent',f,'Style','slider','Position',[81,54,419,23],...
              'value',PARAM_1, 'min',1, 'max',30);
bgcolor = f.Color;
bl1 = uicontrol('Parent',f,'Style','text','Position',[50,54,23,23],...
                'String','1','BackgroundColor',bgcolor);
bl2 = uicontrol('Parent',f,'Style','text','Position',[500,54,23,23],...
                'String','30','BackgroundColor',bgcolor);
bl3 = uicontrol('Parent',f,'Style','text','Position',[240,25,100,23],...
                'String','PARAM_1','BackgroundColor',bgcolor);
b.Callback = @(es,ed) updateSystem(h,TEST_function(es.Value));

When I run the file, Matlab returns the following error:

Undefined function 'updateSystem' for input arguments of type 'matlab.graphics.chart.primitive.Surface'.
Error in TEST>@(es,ed)updateSystem(h,TRANSFER_TEST(es.Value))
Error while evaluating UIControl Callback

I think it has something to do with the surf plot but I'm not able to figure out exactly what it is.

Regards, Mark.

The documentation for 'updateSystem' seems to indicate that 'updateSystem' is expecting a 'handle' object that is mostly the output of a response plot command.
