minmaxsptimes

PURPOSE ^

Find the minimum and maximum of the spike times in each channel

SYNOPSIS ^

function [mintime, maxtime]=minmaxsptimes(data)

DESCRIPTION ^

 Find the minimum and maximum of the spike times in each channel
 Usage: [mintime, maxtime]=minmaxsptimes(data)
 Input:
 data  (spike times as a structural array of channels/trials dimensions; can also accept a 1d 
               of spike times)
 Output:
 mintime       (minimum time across channels)
 maxtime       (maximum time across channels)
