In summary, The conversation is about a problem in Matlab where the user wants to calculate the derivative of an expression that contains abstract functions. The user does not know how to deal with the abstract function and hopes to get the desired result through the use of the Symbolic Math Toolbox. The other person suggests checking if the Toolbox is installed and trying it out.

Hi,I have a problem in Matlab programme,I want to calculate the derivative of a expression by matlab,but there are some abstract functions in that expression.
for example:f=R(t)*cos(t),I want calculate d=diff(f,t),but I don't know how to deal with the abstract function R(t),I hope I can get this kind of result:d=dRt*cos(t)-R*sin(t),but how should I design the programme?
thank you for your help.

Matlab does not do symbolic calculations, without the Symbolic Math Toolbox installed. Do you have that?

Thank you.
I find that I have the Symbolic Math Toolbox installed,I will have a try soon.
