pop

POP removes values from the head of the stack and returns both

Description:
Function to remove values from the head of the stack and returns both.

Syntax:
[Stack, Val]=POP(Stack);

Input Parameters:
o Stack: A one-dimensional column vector used to store neuron indices.

Output Parameters:
o Stack: A one-dimensionalcolumn vector  used to store neuron indices.
o Val: A scalar neuron index obtained from the head of the stack.

Example:
>> Stack=[1];
>> [Stack, Val]=pop(Stack)
