plot the given equation in the interval of x=[-1 3]

y = (10.^(-19)).*(exp((x-(y.*0.1))/0.026)-1)

[KSSV]

What have you attempted for your home work?

[arun p]

this is diode equation

[Walter Roberson]

Yes? And how does that answer KSSV's question ?

I have to say, it does not look like the diode equation to me... https://www.pveducation.org/pvcdrom/pn-junctions/diode-equation The diode equation only has voltage as its input -- unless you are using non-ideal diodes in which case n could be input as well.

Hi arun p

If the equation cannot be expressed explicitly as in y versus x, then such equation is an implicit function, , like the circle equation. To plot an implicit equation, you can use the fimplicit function. For more info, please visit:

fimplicit(@(x,y) y - (10.^(-19)).*(exp((x-(y.*0.1))/0.026)-1), [-1 3 -2 20])

You can compare with the diode plot here:
