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 '.^'.

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

.^ needed for element-wise array operations
0:.01:2*pi splits up the interval into finer steps for plotting

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);
