Plot a function of a differentiation in Matlab

I want to Im = C * (dv/dt) + (V - E)/R, where C, V, E and R are constant. What would be the best way to plot this function of Im. I want to see Im in the y-axis and T in X axis. Do I integrate int(Im)? But how do I plot the function?

I am sort of lost in how to find a matlab function or how I would write a code to illustrate this, can someone provide me some hints? I was told to use Euler loop to perform this.

Thanks.

what is the expression of v ?

Sorry, V is not a constant. V = IR where I is -1.5:0.5:1.5

[Azzi Abdelmalek]

v or V , if they are the same correct your code, v and V are differents variables

 v=-1.5:0.5:1.5
 t=linspace(0,10,length(v))
Im = C * diff(v)./diff(t) + (v - E)/R,

[Robert]

How about in respect of t, where will that go?

[Azzi Abdelmalek]

v=-1.5:0.5:1.5
t=linspace(0,10,length(v))
Im = C * diff(v)./diff(t) + (v - E)/R,
