I want to write this function in matlab,but always wrong.

y=[(-14)*e^( -1500*x )]+[26*e^(-20000*x)]

I written as

y=(-14)*exp.^( -1500*x )+26*exp^(-20000*x)

I don't know where was wrong.

and I want to plot this function.

Hi K ,this is my complete attempt.

y=(-14)*exp(-1500*x )+26*exp(-20000*x)
plot(x,y)

hello

don't forget to define x if you want an output :

x = linspace(0,0.005,500);
y=(-14)*exp(-1500*x )+26*exp(-20000*x);
plot(x,y);
