I'm trying to solve this problem by myself "Animation and Model of Automotive Piston" but I'm getting an error when ploting the graphs as mention in the problem btw pistonheight & crank angle?

Warning: Function behaves unexpectedly on array inputs. To improve performance, properly vectorize your function to return an output with the same size and shape as the input arguments

this is a practice problem in "intro to sybolic math"

Please share your code.

The example appears to refer to https://www.mathworks.com/help/symbolic/examples/animation-and-modeling-of-automotive-piston.html

Akash Vyas comments to me,

Yes, in this problem the first fplot in which theta is varying from 0-2π is showing error in my system

I do not encounter any problem when I execute the example.

I suspect that you might accidentally have an interfering function, from your own code or from some third-party software. Try

restoredefaultpath
rehash toolboxcache

and then try again.
