I am taking Machine Learning course from Coursera. When I run the code in MATLAB(R2017), I am getting error in some optimset function. Error is copied below:
Error using optimset (line 255) Unrecognized parameter name 'GradObj'. Please see the optimset reference page in the documentation for a list of acceptable option parameters. Link to reference page.
How do I resolve this issue.

GradObj is not a valid option to optimset() unless a license is present for one of the following products:
Optimization Toolbox
Curve Fitting Toolbox
Statistics and Machine Learning Toolbox
Computer Vision Toolbox
System Identification Toolbox

Which optimization routine are you trying to call?

Hi Animesh, you can remove the parameter GradObj and its value 'on' from the list of parameters for optimset function, and the code runs without error. i.e. just use options = optimset('MaxIter', 400);
Hope this helps.
