[Scilab-users] "Re-sampling" data and making 2 vectors

[Jaquelineanbarr]

Hello, Im working with matrices with different samplings. 

First data
//time Temp sq 
*091532.0  23220.37 96 *
091535.0  23221.34 95 
091538.0  23220.64 95

Second  data
//X Y elevation Tem sq corrTem sat time massx mssy  line

(is not the complete data, is an example)
My problem is  data1 is longer than data2. With data 1 i have one value of
temperature each 3 seconds, meanwhile in data 2 I have one value of
temperature each half second. 
I have to "cut" the matrixes, they should have the same lenght (because I
need Data2-(Data1-mean(Data1)) , and starts at the comun hour. I dont know
how do it, Any suggest?

The format of the time is for example 072301 (07:23:01)
