??? Error using ==> sym.subs>flatten at 224
Number of elements in NEW must match number in OLD

Error in ==> sym.subs at 146
[X,Y] = flatten(X,Y);

Error in ==> networkadjustment at 185
L0(i)=subs(L01,[a b c d ],[FX(i,1) FY(i,1) TX(i,1) TY(i,1)]);



What is this error for ?
I can not run my program any more.. but before I dont have this error..
I can not run any previous program ..

I tried it into different computers. Both matlabs give me this error
What s happend to my program :(

Another error in another matlab

??? Error using ==> eval
Undefined function or variable 'x30'.

Error in ==> sym.double at 45
D = reshape(eval(X),siz);

Error in ==> networkadjustment at 260
elseif double(Se1(i)) > 0 & double(Se2(i)) > 0 & double(Sa1(i)) >0 & double(Sa2(i)) > 0

:(

Hi, you should make sure that the number of elements in [a b c d] actually matches the number of elements in [FX(i,1) FY(i,1) TX(i,1) TY(i,1)]. Perhaps one or more are empty? The function subs() is issuing an error because the number of elements is [a b c d] does not match the number of elements in [FX(i,1) FY(i,1) TX(i,1) TY(i,1)].

You should put a breakpoint at that function call in networkadjustment.m and see what is being passed to subs().

Hope that helps,
Wayne

One of Se1 or Se2 or Sa1 is a symbolic expression that references a
symbolic variable named x30 which is not defined.
