HP 50G Matrix Writer



#6

Hello

I have to make a Matrix Table in the Matrix Editor to use it with a ANOVA Programm (Statistic). My problem is now that i have Tables with different Lenghts.

eg:

1 2 3 4

5 6 7 8

9 8 7

2 3

If i use this matrix, HP 50g fills in all the empty data points with a 0 (Zero). This makes a wrong result. Can you help me?

Sounds like you need to use Excel and the Data Analysis pack.

Try Google.

Search for "Excel data analysis pack"

and you get lots of hits. Here is the first one:

Link

"The Data Analysis pack is a powerful set of tools used to figure out the variance, correlation and covariance of data as well as other features. Although the Data Analysis pack is a standard feature that comes with Excel, it may not be loaded into Excel. It is usually found under the Tools menu."

To buy Excel, there are lots of options. Amazon, a local store, etc.

Arrays are required to have rectangular dimensions. You'll get syntax errors if you try to input ragged dimensions from the command line as well.

Flag -91, when set, will cause the Matrix Writer to output a list containing each row as a list. You're still mostly limited to rectangular dimensions, however blank cells will be returned as NOVAL, and you can write programs to ignore/remove these null values.

Not sure if that helps you any with the ANOVA program, but maybe there's a partial solution in there somewhere.
