Matrix Library



#8

Hi Marcus
I have found an error (finger trouble probably) in the matrix library - namely in wp34s-1.dat.
The first 'M-' label should read 'M-0'. The real 'M-' appears further down.
For Pauli - in the 'M-y' routine you execute a [cmplx]DROP, which does not leave
a descriptor on the stack. Should this not be just a DROP?
Regards John

BTW- Thanks for these routines. The LU routine (if included) would be great :)

Won't be finger trouble -- these are generated by the assembler from the sources in the library. Still, the source only has one 'M-' label so something has gone awry.

The matrix descriptor is saved in L. The value on the stack isn't the descriptor anymore -- it is a loop index for ISG that has finished. Thus, complex DROP is correct here.

The LU routine will be back if we can find enough space for the wrapper. We're working on it.

#10

Thanks Pauli, should have checked L - I just looked at the comments which said the descriptor was returned in X.
Thanks for the prompt response. I am really enjoying this calculator :)
Regards John


#11

There wasn't a comment on this routine about stack and register use????

I've added some clarification nonetheless. The documentation for these is in the doc directory.


- Pauli


#12

My apologies then, I mistook the comments above, applying to the functions below. Still love this wp34s - great effort and thanks!
Regards John

This must have been my fault when changing names from M. to M- in the (wrong) hope that would ease the navigation of the built-in matrix commands in the catalogs. I assume it has been fixed by Pauli now.

#14

... and at least some of these routines/commands will be renamed soon.
