Create a function to calculate hyperbolic's then graph them?

I need some advice about graphing the hyperbolic sin, cos and tan. Can you create a plot inside a function? well heres what i have... Thanks in advance!

    function [sinh1x,cosh1x,tanh1x] = hyper(X)
    sinh1x=sinh(X);
    cosh1x=cosh(X);
    tanh1x=tanh(X);
    plot(X,sinh1x)
    plot(X,cosh1x)
    plot(X,tanh1x)
    grid on
    end

About the only thing you might want to change is to put a call in to the HOLD function so that all plots appear on the same axis, or pass all the arguments to plot at once. Like this:

function [sinh1x,cosh1x,tanh1x] = hyper(X)
sinh1x = sinh(X);
cosh1x = cosh(X);
tanh1x = tanh(X);
plot(X,sinh1x,X,cosh1x,X,tanh1x)
legend({'sinh(x)';'cosh(x)';'tanh(x)'},'location','northwest')
grid on

Then call it like this:

>> [sinh1x,cosh1x,tanh1x] = hyper(0:.01:1);
