WHERE Get Information on Program Stack

Section: Inspection Functions

Usage

Returns information on the current stack. The usage is 
   where

The result is a kind of stack trace that indicates the state of the current call stack, and where you are relative to the stack.

Example

Suppose we have the following chain of functions. 

     chain1.m
function chain1
  a = 32;
  b = a + 5;
  chain2(b)



     chain2.m
function chain2(d)
  d = d + 5;
  chain3



     chain3.m
function chain3
  g = 54;
  f = g + 1;
  keyboard

The execution of the where command shows the stack trace.
