Dear all,
I minimize this function.
g=randn(1000,1); u=randn(1000,1);ff = @(x) sum( ( g(2:end)- x(1)- x(2)*(g(1:end-1)-x(1)) - u(2:end)*x(3) ).^2 ); xx = fmincon(ff,[0.1 0.2 0.3],[],[],[],[],[],[],@unitdisk3,options);
where
function [c,ceq] = unitdisk3(x)c = [ x(2)-0.999; -x(2)-0.999 ;- x(3) +0.001 ];ceq = [];end
but I get this error message
Error using vertcatDimensions of arrays being concatenated are not consistent.Error in unitdisk3 (line 2)c = [ x(2)-0.999; -x(2)-0.999 ;- x(3) +0.001 ];Error in fmincon (line 633) [ctmp,ceqtmp] = feval(confcn{3},X,varargin{:});Caused by: Failure in initial nonlinear constraint function evaluation. FMINCON cannot continue.
Any ideas why?
