How to plot this function in matlab?

x=e^((y-b)/a)

Answer 1

[John D'Errico]

help exp
help ezplot

Subtract x. Don't have the equality in there. ezplot will assume the result is implicitly equal to zero, but if you put in an equality symbol, it will get confused.

Of course, if b and a are not known, then how do you expect any plot? So, supply some values for b and a FIRST.

Or, just take the log, then solving for y.

Hi Ahmad

with new fplot is even easier

   a=1,b=2;fplot(@(x) exp((x-b)/a))
