I have a data set which when put in a matrix is about 120,000 rows and 4 columns

I want to do an automated sorting and graphing of these with user specifications

such as...when columns 1 and 2 are equal to 0, plot column 3 vs. 4

i have it set up in matlab right now, but what i was doing was if the case above is what i want, delete all the other rows in the matrix and then graph the matrix...this takes hours for matlab to do though for somereadon...i just have a couple while-loops runing so it tests each row.

whats the best program to use for these types of calculations?

i've done it in gnuplot and it can do it fast, but I want a program I can build a user interface off of.

thanx

If you can control matlab through command line or an easy to use automation interface then VB (compiled) or VC++ might be the ticket. Have them generate cut-down datasets using your criteria then run matlab (or gnuplot) on the results.

Or look at Google and codeproject.com for plotting source code and do the plotting insde VB / VC. There are also commercial charting components for them if you don't mind spending money.
