Second derivative of Gaussian function
显示 更早的评论
I would like to be able to get the second derivative of the Gaussian function which can be described as
Gaussian=yo+(A*Const/w*(exp(-log(2)*((X-c)./w).^2)); where Const=sqrt(log(2)/pi)
Can I use the differentiate function for this?
Thanks in advance.

Sure:
syms yo A w X c
Gaussian=yo+A/w*exp(-((X-c)/w)^2);
diff(Gaussian,w,2)
I have cleaned up some redundancy in your expression.
