titles ?

Postby hbarkhof on Thu Jul 25, 2019 8:16 am

Absolute beginners question. Can't find the answer in "Mastering Dyalog APL".

Have a matrix 'test' :
test←5 2 12⍴120 ? 200

defined a column title 'titles' :
titles←'Jan' 'Feb' 'Mar' 'Apr' 'May' 'Jun' 'Jul' 'Aug' 'Sep' 'Oct' 'Nov' 'Dec'

I simply can not figure out how I can have the 'titles' above the matrix.

Very nice would be if someone could show me this and even better , how to add
row titles.

----------------------Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
jaar 2010 | Machine 1
======= | Machine 2
jaar 2011 | Machine 1 DATA HERE
======= | Machine 2
etc.

Thanks for your time.

Henk.

How about:

Code: Select all
      years←2010+⍳5
      months←'jan' 'feb' 'mar' 'apr' 'may' 'jun' 'jul' 'aug' 'sep' 'oct' 'nov' 'dec'
      test←5 2 12⍴120 ? 200

      ((⊂''),months)⍪(,(⍪'jaar '∘,¨⍕¨years),⊂9⍴'='),((2×≢years),≢months)⍴test

Well, I now have 40 years of experience with APL. However, I often feel that I learned 99% of what I know in the first year or so ;-)
