in my script i declare a global variable by
...
global Global_Coeff;
Global_Coeff=Coeff;
where Global_Coeff is a 4x4 matrix containing double values. So far so good. I now want to use these Global_Coeff in the following (different script):
lb=[1,1,1,1,1,1,1,1,1,1,1,1];
ub=[3,3,3,3,3,3,3,3,3,3,3,3];
rng default
x0 = [1,0.9,1.1,0.8,1.2,1.3,0.7,1.11,1.12,0.99,2.1,2.0];
[x,res] = lsqnonlin(@root2d,x0,lb,ub)
where the first four equations of the function root2d look like this:
function F = root2d(x)
F(1) = Global_Coeff(1,1)*x(1)+Global_Coeff(1,2)*x(2)+Global_Coeff(1,3)*x(3)+Global_Coeff(1,4);
F(2) = Global_Coeff(2,1)*x(4)+Global_Coeff(2,2)*x(5)+Global_Coeff(2,3)*x(6)+Global_Coeff(2,4);
F(3) = Global_Coeff(3,1)*x(7)+Global_Coeff(3,2)*x(8)+Global_Coeff(3,3)*x(9)+Global_Coeff(3,4);
F(4) = Global_Coeff(4,1)*x(10)+Global_Coeff(4,2)*x(11)+Global_Coeff(4,3)*x(12)+Global_Coeff(4,4);
...
end
This is the error message i get:
Undefined function or variable
'Global_Coeff'.
Error in root2d (line 6)
F(1) =
Global_Coeff(1,1)*x(1)+Global_Coeff(1,2)*x(2)+Global_Coeff(1,3)*x(3)+Global_Coeff(1,4);
Error in lsqnonlin (line 196)
initVals.F =
feval(funfcn{3},xCurrent,varargin{:});
Error in KMG2Koordinatenform (line 54)
[x,res] = lsqnonlin(@root2d,x0,lb,ub)
How do i pass my variables/4x4Matrix containg my double-values correctly, so my function root2d and the call lsqnonlin can use them?
