I have written a function in MATLAB as follows,

function y= quadfunc(x)

% quadfunc.m is the file name

y=x;

y= quad('quadfunc',0,1)

end

 When I pressed the green play button one error has appeared like this,

>>quadfunc

Error usins quadfunc(line 2)

Not enough input arguements.

Now please help.

Answer 1

Yes .. quadfunc takes exactly one argument. Pass it.

Eq:

quadfunc(5)

You can call the function as above from MATLAB commandline.

If you want to run from editor, then code it to be interactive using

input

command or hard code the value of x.

You have quad('quadfunc') within quadfunc.m . As quad() attempts to invoke the function it is given, it would try to invoke quadfunc, which would try to invoke quad, which would try to invoke quadfunc.... and so on.

Use a different file to hold the call to quad, and call upon that file rather than calling upon quadfunc
