Create a simple test 2D matrix

My HOF mapping skills (such as they are) have left me today :frowning:

I'd like to programatically produce a list of lists matrix combination - for example using lists 1,2,34 and a,b,c,d - to produce:

like this?

or more like this?

Another way (not the best but it work...)

The first one is what I was trying to do but was missing using the concept of using the value from the outer mapping - like I said - my matrix mapping skills left me this morning :slight_smile:


I can now get back to spying / playing with your github list changes.... :slight_smile:
