can any one tell me why that function can not run??

1 次查看(过去 30 天)
n=-5:5;
x=y(n);
x1=y(n-1);
x2=y(n+1);
subplot(3,1,1)
stem(n,x);
grid on;
subplot(3,1,2)
stem(n,x1);
grid on;
And I have the following function
function x=y(n)
x(n)=(n).*(n>=1&n<=5);
end

x(n) = ..
^^^ because of this indexing
Fixed:
n=-5:5;
x=y(n);
x1=y(n-1);
x2=y(n+1);
subplot(3,1,1)
stem(n,x);
grid on;
subplot(3,1,2)
stem(n,x1);
grid on;
function x=y(n)
x = (n).*(n>=1&n<=5);
end

Hi, you obviously did not do any debugging. Your attempt at coding has several issues, but you can easily rectify them if you go obe line of the code at a time and have a look at its result. Matlab provides you a preview of the values of variables and you have the workspace panel with all your variables, where you can see all variables that currently... Use F10 or F11 to step through your code and see the results line by line. It will become much clearer.
