我正在尝试在Octave最新Mac版本中使用optim软件包

Question

我有一个简单的八度音阶脚本

%!  ## Example for linear inequality constraints
%!  ## (see also the same example in 'demo nonlin_residmin')
%!
Ae = 1.5; ale = 0.1; omegae = 0.9 ; phie = 1.5;
noise = 0.1;
t = linspace(0,10,50); 
n = noise*randn(size(t));
function y = f(t,p)
    y = p(1)*exp(-p(2)*t).*cos(p(3)*t + p(4));
endfunction
y = f(t,[Ae,ale,omegae,phie])+ n;
plot(t,y,'+; data;')
% NOW try fit
A0 = 2; al0 = 0; omega0 = 1; phi0 = pi/2 ;
[fr,p] = leasqr(t,y,[A0,al0,omega0,phi0],'f',1e-10);
p 
yFit = f(t,p);
plot(t,y,'+',t,yFit)
legend ('data','fit')

但是我在leasqr软件包中遇到错误 我已经安装了这些软件包

Package Name  | Version | Installation directory

>> testNonlinearfit

error: '__plot_cmds__' undefined near line 296 column 3

非常感谢任何帮助
