Definition: | sequence res = vslice(sequence source, integer column) |
Description: |
Return the specified column of every element of source. |
Comments: | This is sometimes also known as a vertical slice, although that is not entirely correct since you can only extract a single column, so 'vertical subscript' might have been better, but in that case this routine would probably have been named 'vsubscript'. |
Example: |
sequence s = {{5,1}, {5,2}, {5,3}} ?vslice(s,2) -- prints {1,2,3} ?vslice(s,1) -- prints {5,5,5} |
