They will allow you to create column vectors 2, 3, and 4 elements high. The 4-element high vector takes about 3 lines of space, and fits nicely with the brackets @lbr3 and @rbr3. The macros are named "stacknx" where n is either 1, 2, or 3, and x is a symbol which determines which element of the vector is the widest. (For example, @stack4t creates a stack of 4 elements with the top one being the widest.) One bug I have not been able to fix is that there cannot be two "widest" symbols. The way to get around this is to surround one of them by 1/2 spaces (#) and treat that one as the widest. Here is an example: @begin(m) T@ =@ @lbr3@~ @stack4b(t=<1>,mt=<0>,mb=<0>,b=<#0#>)@~ @stack4t(t=<#0#>,mt=<1>,mb=<0>,b=<0>)@~ @stack4t(t=<#0#>,mt=<0>,mb=<1>,b=<0>)@~ @stack4t(t=<#x@down(t)#>,mt=,mb=,b=<1>)@~ @rbr3 @end(m) The matrix created by this is: 1 0 0 xt 0 1 0 yt 0 0 1 zt 0 0 0 1 inside large versions of the brackets [ ] . I hope this helps. If you decide to use these and have any further questions, please let me know. Ellen
