[Matlisp-users] (SETF (MATRIX-REF ...) ... ) problem?

[Michael A. K. <ma...@ll...>]

When using MATRIX-REF to set sub-matrixes of type COMPLEX-MATRIX  from 
type COMPLEX-MATRIX I get an error.

Type REAL-MATRIX from REAL-MATRIX is okay.

Type COMPLEX-MATRIX from REAL-MATRIX is okay.

The following code segment shows this.  I'm using 
matlisp-2.0beta-2003-10-14.tar.gz under FreeBSD 4.9.
I suspect the problem is in REF.LISP but haven't tracked it down.  Can 
anyone help?

tnx
