Wed 02 Aug 2023 07:21:55 PM UTC, original submission:  

Jacobian output caused an error message.

Example:

xdata=(pi/2)*[-1 -1/2 0 1/2 1]';
ydata=cos(xdata);
x0=0;
fun=@(x,xdata) x*cos(xdata); 
[x, resnorm, residual, exitflag, output, lambda]=lsqcurvefit (fun, x0, xdata, ydata)
[x, resnorm, residual, exitflag, output, lambda, jacobian]=lsqcurvefit (fun, x0, xdata, ydata)

Outputs from the first call:

x = 1.0000
resnorm = 6.6566e-23
residual =

  -3.5325e-28
  -4.0794e-12
  -5.7692e-12
  -4.0794e-12
  -3.5325e-28

exitflag = 3
output =

  scalar structure containing the fields:

    iterations = 4

lambda = [](0x0)


Error message from the 2nd call:

error: 'settings' undefined near line 309, column 37
error: called from
    lsqcurvefit at line 308 column 10
