I've created a script that creates 10 random vectors between 1 and 100 and the function I have below is supposed to count how many of each between certain values. however, when I run it from the editor it says not enough input values. also when I run it from the command windows it just says ans=0 rather than the 3 values it should give.

function[r1, r2, r3] = func22(vector)
r1=sum(vector>=1 & vector<=25);
r2=sum(vector>=25 & vector<=75);
r3=sum(vector>=75 & vector<=100);

any ideas of why it says no input values in editor and why it only gives one answer in the command window.

在 MATLAB Online 中打开

Do not click the green button. Call your function like this:

[r1,r2,r3] = func22(vector)

with an appropriate input argument and you will get three outputs, e.g.:

 >> [out1,out2,out3] = func22(1:20:1e4)
 out1 =  2
 out2 =  2
 out3 =  1

or whatever.

so to call a function with multiple outputs you need to put the outputs before it when you call it.

Yes, this is what I just showed you, and this is exactly as the MATLAB introductory tutorials explain (you have done the introductory tutorials, I hope):
