MATLAB: How to display MAPE in gui

mape

for example value for mape is 50:

 mape = 50;
 set(handles.text10,'String','MAPE = '+mape_2);

In GUI I have lot of different values, but I need only one value – 50. Please I need help!

and mape as text is not here too. I have only this on my gui – picture

Dominika - why is one variable named mape but then you reference mape_2 where you set the string of the text10 control? If you are trying to update the text string with a combination of 'MAPE =' and 50 then try doing the following

 mape = 50;
 set(handles.text10, 'String', ['MAPE = ' num2str(mape)]);

In the above, we use num2str to convert the number into a string and then concatenate it with 'MAPE =' using the square brackets.

MATLAB: Adding MAPE/RSME to subplot

Try something like this

f = figure();
% random values
MAPE = [1.234 2.123 1.034 0.234];
MSE = [2.20 1.20 2.23 1.10];
R2 = [0.9 0.7 0.8 0.9];
% make random graphs
ax = gobjects(1,4);
for i=1:4
    ax(i) = subplot(2,2,i);
    plot((1:10)+2*rand(1,10));
    xLeft = ax(i).XLim(1);
    xDiff = diff(ax(i).XLim);
    yTop = ax(i).YLim(2);
    yDiff = diff(ax(i).YLim);
    text(xLeft+0.05*xDiff, yTop-0.05*yDiff, ['MAPE=' num2str(MAPE(i))], ...
        'HorizontalAlignment', 'left', 'VerticalAlignment', 'top', 'Interpreter', 'latex');
    text(xLeft+0.05*xDiff, yTop-0.15*yDiff, ['MSE=' num2str(MSE(i))], ...
        'HorizontalAlignment', 'left', 'VerticalAlignment', 'top', 'Interpreter', 'latex');
    text(xLeft+0.05*xDiff, yTop-0.25*yDiff, ['$R^2$=' num2str(R2(i))], ...
        'HorizontalAlignment', 'left', 'VerticalAlignment', 'top', 'Interpreter', 'latex');
end
