I have a matrix of data [ trial, block, IV1, IV2, IV3, DV ]. I want to create a new variable based on the different levels of IVs 1-3 for multiple subjects.
n: 6
trials: 384
blocks: 8
IV1: 3 levels
IV2: 2 levels
IV3: 2 levels
new variables wold have 12 conditions.

As 3,4,5 columns are your IV values, you can create a new column using your data.
If your table name is temp. You can do it like
temp(1,7) = temp(1,3) + temp(1,4) * temp(1,5) (7 here indicates new column)
That will create a new column in the table and fill it using your desired value.
