function precedence

[Ron Crummett]

Hi -

Is there any way to specify calling precedence of a function?  For 
example, I have written a function that performs upsampling similar to 
the matlab upsample function.  Yet when I make a call to upsample, it 
calls a function by the same name that I wrote several years ago -- and 
does not yield the desired result.  My current remedy is to rename the 
undesired function, but this is something I have run into multiple 
times.  Is there a way to determine which function receives calling 
precedence?  I hope this makes sense.  In the event that it helps, I am 
running 2.1.73 on Kubuntu breezy.
