Matrix multiplication in dasylab

[donrafa7]

Can dasylab perform matrix multiplication?

[CJ_Butler__DASYLab_Pro]

My initial impression is no, DASYLab cannot do that. 

Having said ,that, what would the functions look like? 

[donrafa7]

It would be a 6x6 multiplied by 6x1 matrix.   Basically running a 6dof load and want to see the loads realtime.

[donrafa7]

The 6x6 would be a constant and the 6x1. Would be 6 voltages from strain gage

maybe the formel interpreter in mathematics can help with that:

6 inputs (x-vector)

6 outputs (y-vector)

36 global variables (A(i,j)-matrix - constant for the module)

for each output the formula would be

y(0)=OUT(0) :

IN(0) * ${VAR_1} + IN(1) * ${VAR_2} ... + IN(5) * ${VAR_6}

y(1):

IN(0) * ${VAR_7} + IN(1) * ${VAR_8} ... + IN(5) * ${VAR_12}

etc...

A(i,j) is stored in global variables row after row A(1,1)->1, A(1,2)->2, (2,1)->7 ...

this is just a suggestion to try - not tried by myself. 🙂

if that does not work, the python module would definitely will do the job.

THis worked well.  thanks

I have created an example worksheet (works with DASYLab 13, and 2016).
