Normally, I would write something like: function[VR,VC]=RC(V,R,C,t)Description. fcontour (f) plots the contour lines of the function z = f (x,y) for constant levels of z over the default interval [-5 5] for x and y. fcontour (f,xyinterval) plots over the specified interval. To use the same interval for both x and y , specify xyinterval as a two-element vector of the form [min max].You need to assign equal vector length value to t as of x . However, I believe, you need to replace x with t in your equation. y= (25*sin (3)*x); # will plot a straight line since you have a constant sin (3) # which you are just multiplying with x resulting in x verses constant x. I assume you want to write the equation as.To plot an anonymous function, you must use “fplot” even if your function is not named "f".
