x = 0:1:30;

y = ((30^x)*exp(-30))/factorial(x);

plot(app.UIAxes,x,y);

the graph is not plotting, can anyone assist with this.

Shu-An - when I run your code, I see the following error

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 '.^'.

Error in yy (line x)
y = ((30^x)*exp(-30))/factorial(x);

If you do an elementwise operation, try changing your y assignment to

y = ((30.^x)*exp(-30))./factorial(x);
