Maybe as a workaround you could use these wrappers: function matrix alwaysRe(const matrix m) return iscomplex(m) ? Re(m) : m end function function matrix alwaysIm(const matrix m) return iscomplex(m) ? Im(m) : m end function I've also noticed that sqrt still doesn't work on matrices with negative numbers. Of course not strictly necessary, but since the root of -1 is the definition of i, feels a little strange. thanks sven _______________________________________________ Gretl-users mailing list -- gretl-users(a)gretlml.univpm.it To unsubscribe send an email to gretl-users-leave(a)gretlml.univpm.it Website: https://gretlml.univpm.it/postorius/lists/gretl-users.gretlml.univpm.it/
