Matrice operation (v1[x] = v[0][x] - v[1][x])

[TouEnMasm]

Hello,
Is someone  have written macros to solve this form of operations: v1

• = v[0]
• - v[1]
•     ?

Hi Yves!

Using macros in mtx.inc : http://masm32.com/board/index.php?topic=8398.0. Requiere JWasm family because there are macros creating macros.

Using Matrix.inc in ObjAsm: http://masm32.com/board/index.php?topic=8583.0.  Examples of use are in ObjAsm32. This Matrix.inc is a modification in progress of that.

A litle more specific and in development, perhaps using a more advanced mtx.inc (I have to see ). Also in ObjAsm I'm translating some C++ code:

I expected the kind of matrice masm macro you use, when cpu don't support dotproduct
D3d matrices library

[TouEnMasm]

I search Macro to do it.My prefered method is to let it done by the c compiler (mixed langage c asm).
Perhap's smplmath is abble to do it but i need a demo.
After stay to write macro to do that.

I search Macro to do it

Only macros in Mtx.inc

Perhap's smplmath is abble to do it but i need a demo.

It's not SmplMath and, because macro expansion, only work with SmplMath in limited cases. Of course, is very interesting when can work together, how you can see in some Hydrograph lines.

Don't need SmplMath:

fild v2
                        fmul varD
                        fsub descargaunidad(v1ant, 0)
            fld descargaunidad(v1, 0)
                fsub descargaunidad(v1ant, 0)
                fdiv
                fld descargaunidad(v1, 1)
                fsub descargaunidad(v1ant, 1)
        fmul
                fadd descargaunidad(v1ant, 1)
fstp tablero2(v2, 0)

In this case I'm using real8, but you can use any type or structure.

If you have no mind for this advanced matrix  (or you are using ML), you still can use the 20 years old method  :

Code Select Expand

        matrix macro p1 , p2 , p3, regaux, no1
            mov  eax ,  p3
            imul p1
            add  eax , p2
            ifb <no1>
                ifnb <regaux>
                    mov  &regaux , eax
                else
                    mov  ebx , eax
                endif
            endif
        endm


Code Select Expand

.data
            mat_ET1 dd 100 dup (0)
   
            mat_ATL_max equ 3
            mat_ATL real4 3*100 dup (0.0)

            mat_UTL_max equ 4
            mat_UTL real4 4*100 dup (0.0)
.code
            ···
            fild mat_ET1[ecx*4]
            matrix nn, 0, mat_ATL_max
            fst real4 ptr mat_ATL[ebx*4]
            fstp real4 ptr mat_UAT[ebx*4]
            ···

This is used in now corrected http://masm32.com/board/index.php?topic=9439.msg103363#new
