if size(cost,1) == 2
A = (4*Pdt*cost(1,3)*cost(2,3)) + 2*(cost(1,2)*cost(2,3))+(cost(1,3)*cost(2,2));
B = 2*(cost(2,3)+cost(1,3));
lambda = num2str(A ./ B);
set(handles.answer1_staticText,'String', lambda);
P1 = (lambda - cost(1,2))./(2*cost(1,3));
P2 = (lambda - cost(2,2))./(2*cost(2,3));
PT = mat2str(P1 + P2);
set(handles.answer2_staticText,'String', PT);
guidata(hObject, handles);
end
From the coding above, the answer become like this :
[11.75 11.25 11.25 11.75 10.75 11.5 12.75 12.75 13]
My question is I want to display my answer at the static text box like this:
P1 = (%answer for P1)
P2 = (%answer for P2)
P TOTAL = (%answer for PT)
Can anyone help me with the coding?

You can build the multiline text, for example:
{['P1 =' string1],['P2 =' string2],['P3 =' string3]}

If I interpret your question correctly, you're asking how to get the nicely formatted output in the text box. If that's the case, use sprintf instead of mat2str to define the string PT before using set.

Similar code with sprintf:
PTM=sprintf('P1=%s\nP2=%s\nPT=%s',mat2str(P1),mat2str(P2),mat2str(P1+P2));
set(handles.answer2_staticText,'String', PTM);

No worries, I just wanted to make sure I was answering the right question! Paulo's response is what I was thinking - the key being the use of \n to get line breaks. (Thx Paulo)
BTW, another way to get multiple lines is the use char(10) to print a line break: txt = ['string1',char(10),'string2']

function multilinetext
hf = figure;
uicontrol(hf,'style','pushbutton','string','update',...
'position',[100,100,60,20],'callback',@updatetxt);
hin = uicontrol(hf,'style','edit','position',[100,140,200,20]);
hout = uicontrol(hf,'style','text','position',[100,180,200,60]);
function updatetxt(~,~,~)
txt = get(hin,'string');
x = str2num(txt);
y = 2*x;
strng = ['x = ',txt,char(10),'y = ',mat2str(y),...
char(10),'sum = ',mat2str(x+y)];
set(hout,'string',strng)
end
end

this was just a standalone function to show how to use char(10). without your full code, I can't really test an answer to be sure that it will work, but I'll give it a go...

I used the exactly same code but had to use other values because I have no idea what's that Pdt and cost, I just commented the first lines and used P1=[1 2 3];P2=[4 5 6]

I believe the problem is related to the type of object, if you have edit text boxes you might have to change the Max value property, this is from the Matlab Help:
If the edit text Max and Min properties are set such that Max - Min > 1, the user can enter multiple lines. For example, setting Max to 2, with the default value of 0 for Min, enables users to enter multiple lines.

Try this (as a cut/paste replacement of the code you posted):
if size(cost,1) == 2
A = (4*Pdt*cost(1,3)*cost(2,3)) + 2*(cost(1,2)*cost(2,3))+(cost(1,3)*cost(2,2));
B = 2*(cost(2,3)+cost(1,3));
lambda = num2str(A ./ B);
set(handles.answer1_staticText,'String', lambda);
P1 = (lambda - cost(1,2))./(2*cost(1,3));
P2 = (lambda - cost(2,2))./(2*cost(2,3));
string1=mat2str(P1);
string2=mat2str(P2);
string3=mat2str(P1+P2);
set(handles.answer2_staticText,'String',...
['P1 = ',string1,char(10),...
'P2 = ',string2,char(10),'PT = ',string3]);
guidata(hObject, handles);
end

ah, i think i finally understand what's going on here. answer2_staticText isn't actually a static text uicontrol -- it's an editable text uicontrol, right? uicontrol of style 'text' doesn't have the multiline restriction; style 'edit' does.
