One trick is to wrap the matrices inside a framed environment and putting the location parameter there: \starttext \startformula \startmatrix[left={\left(},right={\right)}] \NC A \NC B \NR \NC C \NC D \NR \stopmatrix = \startframed[location=top,frame=no,offset=none] \startmatrix[left={\left(},right={\right)}] \NC A \NC B \NR \NC C \NC D \NR \stopmatrix \stopframed = \startframed[location=bottom,frame=no,offset=none] \startmatrix[left={\left(},right={\right)}] \NC A \NC B \NR \NC C \NC D \NR \stopmatrix \stopframed \stopformula \stoptext

Signierter PGP-Teil Hi all,

Thank you for your recent assistance with calligraphic math fonts.

I am trying to use a matrix example from math-ali.mkxl, but I am running into an issue. When I try to use the location parameter, I receive the error A <box> was supposed to be here.

I have also tried both location=bottom and location=top, but both give the same error.

Do you have any ideas on how I can get the matrix in the desired locations? Thank you in advance for your help.

Best regards, Jacob
