Not sure what's happening here. I was checking documentation for a while and can't seem to find a solution. Here is my function:

 function Q = heatc(c1,m1,t1,t2)
 Q = c1.*m1.*(t2-t1);
 end

Then when I call it I get the following error:

 EDU>> y = heatc(4190,0.185,20,100)
 Undefined function 'heatc' for input arguments of type 'double'.

Not sure what's up, isn't every variable automatically of type floating point double.

A. Did you name the file containing the source heatc.m?

B. Remember that Matlab is case-sensitive while the OS may or may not be.

C. Is the subdirectory in which you created the m-file on the Matlab search path?

are the most obvious causes to investigate first.

Issue was C. Thought I was in the search path. Thanks.
