Graph.m error - undefined function error Help!

I am trying to run a code in my matlab software but it gives me an error. It says:

Undefined function 'graph' for input arguments of type 'double'.

Error in lab2 (line 25)
 graph(1,311,t,g,TimeAxes, 't(s)', 'g(t)','a sinusoid');

I am not sure how to fix this. Please help.

Answer 1

You need to define graph. Put this line before that line and see what it says

which -all graph

Answer 2

Says

 'graph' not found.

Well, there's your answer.

By the way, you should have put that as a comment to my answer since it's not an Answer in itself to your original question.

Next step: locate graph function, or someone who can provide it to you.

As a clarification: graph() is not a MATLAB routine.
