hi, I have the following function g with the values of x
x = linspace(-2,2)
G = @(x) exp(x) .* (x <= 0) + sin(2*pi*x)./max(x,realmin) .* (x>0);
I tried to plot G using
plot(G,x)
but I am getting error. How can I plot G?

Since ‘G’ is a function handle, you cannot plot it.
You need to call it as a function and plot its output, so plot it either as:
plot(G(x), x)
or:
plot(x, G(x))
depending on what you want.
