Unsure what I did wrong

I want to plot a graph of y against x:
x=[0:2*pi] 
y=exp(1)^x

plot(x,y)

But this error showed:

Error using ^ (line 51)

Incorrect dimensions for raising a matrix to a power. Check that the matrix is

square and the power is a scalar. To perform elementwise matrix powers, use '.^'.

Answer 1

[David Hill]

x=0:.01:2*pi;
y=exp(1).^x;
plot(x,y)

what does the change mean? thanks

[David Hill]

.^ needed for element-wise array operations

0:.01:2*pi splits up the interval into finer steps for plotting

Answer 2

[Steven Lord]

Don't try to raise exp(1) to the power of x. Just use exp on the array x directly.

x = 1:5;
y = exp(x);

[David Hill]

Yes!
