helloiam making a force analysis program the prog first takes some data from the user and then gets the unknown forces through 2 matrices V=a\b where a is the coeff matrix and b is the constant matrix the problem is the user is asked to enter 1 value of theta and it works fine give the forces at this theta but when i insert theta as th2=0:1:360 give a CAT arguments dimensions are not consistent.error i want to get the forces and get the corresponding theta and then plot them ..... any help would be great thnx in advancethe code is a push button callback axes(handles.axes1) th2=[1:360]; alp2=handles.edit4; l2=handles.edit1 ; r2=handles.edit10; w2=handles.edit3; m2=handles.edit5 ; u=handles.edit9 ; l3=handles.edit2 ; r3=handles.edit11 ; m3=handles.edit6; fp=handles.edit14; e=handles.edit8; m4=handles.edit7; th2r=th2*(pi/180); i3=get(handles.text56, 'string'); i3n=str2double(i3); i2=get(handles.text55, 'string'); i2n=str2double(i2); %%%%%%%%%%%%%Velocity and acc

plot(th2,T) %%%%%%%%%%%%%%%%%%%%%%%
this is the whole code dont know how to get T as a vector and plot it with th2 the values above are entered from the user expect th2 is an iteration the error mssg is ??? Error using ==> vertcat CAT arguments dimensions are not consistent. Error in ==> GUIWORK>pushbutton3_Callback at 757 A=[1 0 -u 0 0 0 0 0; Error in ==> gui_mainfcn at 96 feval(varargin{:}); Error in ==> GUIWORK at 43 gui_mainfcn(gui_State, varargin{:}); Error in ==> @ (hObject,eventdata)GUIWORK('pushbutton3_Callback',hObject,eventdata,guidata(hObject)) ???
