Approved for inclusion in a future ANSI M[UMPS] language standard as part of the library for Matrix Mathematics.
This function creates a (sparse) unit matrix.
SET X=$%MTXUNIT^MATH(.RESULT,4) will create a "full" 4x4 unit matrix:
1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1
SET X=$%MTXUNIT^MATH(.RESULT,4,1) will create a "sparse" 4x4 unit matrix: (a cell containing "#" means no defined value):
1 # # # # 1 # # # # 1 # # # # 1
